A teenager is fighting for his life after being crushed by a concrete pipe at a newbuild estate.
The 17-year-old suffered head and neck injuries when the heavy item toppled onto him while he was working at a building site in County Durham.
Emergency services rushed to Bellway's Sniperley Park DH1 homes development, where groundworks were being carried out by principal contractor Esh Group, just before 1pm on Thursday.
The teen was given first aid at the scene before being taken to the Royal Victoria Infirmary in Newcastle, where he remains in serious condition.
Durham Police and the Health and Safety Executive have launched an investigation into the incident.
A Bellway spokesperson said: 'We are aware of an incident at our DH1 development involving a contractor working for the principal contractor.
'The contractor is assisting the police and the Health and Safety Executive with their enquiries.
'Our thoughts are with the contractor, his family, friends and colleagues at this time.'
