The FBI used billing records from an internet social media app to unmask US airman Jack Teixeira as a suspect over the leak of top-secret military documents, it has been revealed.
Court documents made public on Friday showed investigators identified the Massachusetts Air National Guardsman, 21, using information on the Discord chat platform.
The leak is believed to have started on its servers, which are frequently used by people who play online games.
Classified information is said to range from briefing slides mapping out military positions in Ukraineto consideration of what circumstances Russian President Vladimir Putin might use nuclear weapons.
Discord said it was cooperating with the bureau according to an FBI affidavit unsealed on Friday.
The document says the FBI interviewed an unnamed person familiar with Teixeira’s posts on Monday.

Teixeira is said to be “at the heart” of a private channel called Thug Shaker Central, allegedly posting about guns, games, jokes and memes, people who say they chatted with him have claimed.
The anonymous person told the FBI a username linked to Teixeira began posting what appeared to be classified information last December.

The affidavit suggests Teixeira had been typing out documents in his possession but started taking them home and photographing them after becoming “concerned he may be discovered making the transcriptions in the workplace”.
However, others said the user, nicknamed “the O.G” – also known as “original” or a way to describe someone who is the founder or influential in a group – had been posting documents he said were classified in the group for months.
The O.G started posting images of documents because they were annoyed others were not taking them seriously, it is alleged.

Teixeira was detected on 6 April, according to the affidavit – the same day the New York Times first published a story about the classified documents being leaked.
He was arrested on Thursday by heavily armed tactical agents after a week-long investigation into the disclosure of the highly sensitive government records.

Leaked documents ’embarrassing’ for US
The leaked documents have not been individually authenticated by officials.
A US Defence Department official said Teixeira could have had a higher level of security clearance due to being an information technology specialist responsible for military communications networks.
The Pentagon will now conduct a review of its intelligence access, accountability and control procedures to prevent such a leak from happening again, said US Defence Secretary Lloyd Austin.
Venezuela has accused Donald Trump of making a “colonial threat,” after the US president said the airspace “above and surrounding” the country should be considered closed “in its entirety”.
Mr Trumpmade the declaration amid growing tensions with president Nicolas Maduro – and as the US continues attacking boats it claims are carrying drugs from Venezuela.
He wrote on Truth Social: “To all Airlines, Pilots, Drug Dealers, and Human Traffickers, please consider THE AIRSPACE ABOVE AND SURROUNDING VENEZUELA TO BE CLOSED IN ITS ENTIRETY.”

Venezuela’s foreign affairs office called it a “colonial threat” and “illegal, and unjustified aggression,” and accused the president of threatening “the sovereignty of the national airspace… and the full sovereignty of the Venezuelan state”.
It added that Mr Trump’s words were part of a “permanent policy of aggression against our country” that breached international law and the UN Charter.
The Pentagon and the White House have so far not given any additional detail on the president’s statement, but it marks the latest escalation in tensions between the North and South American countries
Last week, the American aviation regulator warned of a “potentially hazardous situation” over Venezuela due to a “worsening security situation”.

Venezuela then revoked operating rights for six major airlines, which went on to suspend flights to the country.
Mr Trump warned a few days ago that land operations against alleged Venezuelan drug traffickers would begin “very soon”.
Such a move would be a major escalation in Operation Southern Spear – the US naval deployment in the Caribbean Sea and eastern Pacific that has so far attacked at least 21 vessels.

Venezuela claims Trump creating ‘fables’ to justify ‘war’
The Pentagon has sought to justify the strikes by labelling the drug gangs as “foreign terrorist organisations” – putting them on par with the likes of al Qaeda.
It claims the boats targeted are carrying drugs bound for the US, although Sky’s chief correspondent says the final destination is likely to be Europe and West Africa.
The US is also offering a reward of $50m for the arrest of the Venezuelan president, who has been indicted in American courts on federal charges of narco-terrorism and conspiracy to import cocaine.
Mr Maduro has denied Mr Trump’s claims that he is involved in the drugs trade himself and said his counterpart wants to oust him so he can install a more sympathetic government.
Venezuelan officials have also claimed Mr Trump’s true motivation is access to the country’s plentiful oil reserves.
Mr Maduro, who has been president since 2013, has been accused of being a dictator who has cheated in elections.

Around 100-150 people had gathered to celebrate a child’s birthday.

Although the investigation is still under way, Sheriff Withrow said there appeared to have been “multiple shooters” who began the attack indoors and then moved outside.
The shooting was “not a random act”, he said. “They walked into this area and were probably looking for somebody in particular.”
He confirmed that guns had been found on the roof of a nearby building but it was too early to say whether they were “related to this crime”.
