Northern Ireland police data leak: Every PSNI officer has data compromised in ‘monumental’ breach due to human error
The Police Service of Northern Ireland (PSNI) has apologised for a self-inflicted security breach which has compromised the data of every serving officer and member of staff.
The service inadvertently published the information in response to a Freedom of Information (FOI) request on Tuesday.
The breach involved the surname, initials, the rank or grade, the work location and departments of all PSNI staff, but did not involve the officers’ and civilians’ private addresses.
It also reveals members of the organised crime unit, intelligence officers stationed at ports and airports, officers in the surveillance unit and almost 40 PSNI staff based at MI5’s headquarters in Holywood, the Belfast Telegraph reports.
PSNI officers have been the targets of republican paramilitaries in recent years and in March the terror threat level in Northern Ireland was raised to severe.
It comes just hours after the Electoral Commission revealed “hostile actors” managed to hack its systems, exposing the data of more than 40 million voters.
PSNI Assistant Chief Constable Chris Todd apologised for the latest breach, saying: “I’ve had to inform the Information Commissioner’s office of a significant data breach that we’re responsible for.
“This is unacceptable.”
He said it was a result of “human error” with the people involved in the process having “acted in good faith”.

‘Human error’ to blame for data breach
Mr Todd said the information was mistakenly made public for approximately two and a half to three hours after being published at 2.30pm on Tuesday afternoon.
The data breach was brought to his attention at 4pm and was then taken down within the hour.
He added the leak was “regrettable” and that steps had been identified to avoid a similar error from happening again.
Data breach plays into hands of those who deem officers of the crown legitimate targets
It would be difficult to exaggerate the scale of what the Police Federation is calling a “monumental” data breach.
Northern Ireland is the one part of the UK where the terror threat level has been raised from substantial to severe, meaning attacks are highly likely.
That threat comes from dissident Irish republicans, the self-styled New IRA in particular, a conglomerate of breakaway factions still pursuing Irish unity by violent means.
The release of the names and ranks of an estimated 10,000 serving police officers and civilian staff plays right into the hands of those who deem officers of the crown legitimate targets.
Earlier this year, the New IRA claimed responsibility for a gun attack on Detective Chief Inspector John Caldwell in Omagh – he was shot and seriously injured.
Police officers I’ve spoken to say they’re required to implement rigorous data protection protocols and are furious their own data has been breached.
Chief Constable Simon Byrne is under pressure to cut short his holiday and return to Northern Ireland.
Given that the security of his officers and their families should be his top priority, he would be wise to do so.

Chris Heaton-Harris, the Northern Ireland Secretary, has said he is “deeply concerned” about the breach.
Writing on X (formerly Twitter), he said: “My officials are in close contact with senior officers and are keeping me updated.”
How did the breach occur?
Explaining how exactly the breach happened, Mr Todd said: “What’s happened is we’ve received a Freedom of Information request, that’s quite a routine inquiry, nothing untoward in that.
“We’ve responded to that request, which was seeking to understand the total numbers of officers and staff at all ranks and grade across the organisation, and in the response, unfortunately, one of our colleagues has embedded the source data, which informed that request.
“So, what was within that data was the surname, initial, the rank or grade, the location and the departments for each of our current employees across the police service.”
When asked how useful the information would be to terrorist organisations, Mr Todd said the breach is of “significant concern” to many colleagues and information on how they can protect their own personal security has been passed down.

What will happen now?
The Information Commissioner’s Office (ICO) has been notified about the incident.
An ICO spokesperson said: “The Police Service of Northern Ireland has made us aware of an incident and we are assessing the information provided.”
The Belfast Telegraph initially reported the breach, after the newspaper was made aware of the spreadsheet by the relative of a member of police staff.
It reported the spreadsheet had the response to the FOI about police staffing numbers in one tab – with the source information mistakenly included in another.
What reaction has there been?
Liam Kelly, chair of the Police Federation for Northern Ireland (PFNI), described the security breach as “monumental”.
He added: “Even if it was done accidentally, it still represents a data and security breach that should never have happened.
“Rigorous safeguards ought to have been in place to protect this valuable information which, if in the wrong hands, could do incalculable damage.
“The men and women I represent are appalled by this breach. They are shocked, dismayed and justifiably angry. Like me, they are demanding action to address this unprecedented disclosure of sensitive information.
“We have many colleagues who do everything possible to protect their police roles.
“We’re fortunate that the PSNI spreadsheet didn’t contain officer and staff home addresses, otherwise we would be facing a potentially calamitous situation.”
The DUP’s Policing Board representative, MLA Trevor Clarke, said the extent of the data breach in the PSNI is “unprecedented” and “deeply alarming”.
He added: “The public will be rightly seeking answers and they deserve to see a robust response from the PSNI senior command.”
The UUP representative on the Policing Board of Northern Ireland, MLA Mike Nesbitt, has called for an emergency meeting to discuss the breach, while Alliance leader Naomi Long MLA said it was of “profound concern”.
Liverpool have won the Premier League title after a 5-1 victory over Tottenham at Anfield.
Arne Slot’s men did it in impressive style, turning over Spurs in a convincing win.
It was a rocky start for the Reds after Dominic Solanke put the north London side ahead.
However, fortunes quickly changed in the first half as Liverpool scored three times without a response.

In the second half, it took until the 63rd minute for Mohamed Salah to make it 4-1 before a fifth followed.
The Reds have won the title in manager Arne Slot’s first season in charge, and move level with fierce rivals Manchester United on 20 league championships.
But it makes them arguably the most successful English club ever as they have won more European Cup or Champions League titles.
Liverpool captain Virgil van Dijk told Sky Sports after the final whistle: “It’s special and it’s something that we don’t take for granted. It’s amazing.
“A lot of emotions before the game, during the whole week, but we got the job done and we (are) truly deserved champions of England. (Liverpool is) the most beautiful club in the world and I think we deserve all of this. Let’s enjoy the next couple of weeks and let it sink in.”

Slot took over last summer from Jurgen Klopp, who guided them to their previous and maiden Premier League title triumph in 2020, when the COVID-19 lockdown saw matches played behind closed doors.
He is the first Dutch manager to win the Premier League and the fifth man to do so in a debut campaign after Jose Mourinho, Carlo Ancelotti, Manuel Pellegrini, and Antonio Conte.
Speaking to Sky Sports he said: “They [the players] did an outstanding job today. The main job was to win. Everyone said we had got it already. But we had to make sure and we got over the line.”
Several players, including Alisson Becker, Trent Alexander-Arnold, Virgil van Dijk, and Mohamed Salah, played leading roles in both the 2025 and 2020 campaigns.
Van Dijk and Salah recently signed new contracts extending their careers at the club.

Liverpool will have to wait until the final game of the season – at home to Crystal Palace on 25 May – to be presented with the Premier League trophy.
It will be the first time the club’s fans will have seen their side lift the top-flight title in person since 1990.

Two pro-Palestinian demonstrators have thrown red powder on Tower Bridge – just moments before leading runners in the London Marathon went past.
The protesters were arrested on suspicion of causing a public nuisance and remain in custody, said the Metropolitan Police.
A video shared by Youth Demand, which is calling for a trade embargo on Israel, shows two people jumping over a barrier that separates spectators from the race course.
The pair, wearing t-shirts that say “Youth Demand: Stop Arming Israel”, are then seen standing in the middle of the road on the bridge.

They throw red powder in the air as an official marathon car goes past displaying the race time.
A motorbike with a cameraman on board continues along the route, while a second motorbike stops and one of the riders gets off and pushes the pair out of the way, just before the men’s elite runners pass.
Several police officers then jump over the barrier and detain the pair, the footage shows.
There appeared to be no impact on the marathon.
More than 56,000 participants were expected to take part in the 26.2-mile race through the capital.
Sabastian Sawe of Kenya won the men’s elite race in a time of two hours, two minutes and 27 seconds, while Ethiopia’s Tigst Assefa shattered the women’s-only world record in two hours, 15 minutes and 50 seconds.
Assefa beat the previous best of two hours, 16 minutes and 16 seconds set last year in London by Kenyan Peres Jepchirchir.

The Metropolitan Police said in a statement: “At around 10.38am, two protesters from Youth Demand jumped over barriers at Tower Bridge and threw red paint on to the road.
“Marathon event staff intervened to remove the protesters from the path of the men’s elite race which was able to pass unobstructed.”
The force added that they were “quickly supported by police officers who arrested the protesters on suspicion of causing a public nuisance”.
The Met said the paint “appeared to be chalk-based” and was not expected to “present a hazard to runners yet to pass this point”.
