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.
