A 12-year-old boy has died after a garage wall collapsed at a property in seaside town Clacton in Essex.
Emergency services were called to St John’s Road just before 7pm on Friday night.
The boy died at the scene despite efforts to save him, police said.
Another man, 30, was rescued from the rubble and suffered an arm injury during the incident.
Their identities have not been released but both were known to each other, Essex Police said in a statement on Saturday.
The boy’s death is being treated as non-suspicious and a file will be prepared for the coroner.
The house the garage was attached to has been declared safe.
St John’s Road was closed during the incident.
Detective Inspector James Hardingham, who is leading the investigation, said his thoughts are with the family and friends of the boy.
“We’re continuing our enquiries to establish the facts leading to the wall collapse.
“If anyone has information that can help us, or anyone who was in St John’s Road just before 7pm last night and saw anything that could help our investigation, please call us.”
Essex County Fire and Rescue Service station manager Nick Singleton added: “This is a tragic incident and our thoughts are with everyone who knew the child as well as the wider Clacton community.
“Our firefighters worked incredibly hard to save both casualties and this is never the outcome we want to see.
“We will be offering further support to all of the firefighters who attended this difficult incident.”
