Two boys were seriously injured yesterday when they fell through the roof of a disused industrial building in Cheltenham.

One of the teenagers was flown by air ambulance to Southmead Hospital, Bristol and the other was driven by ambulance to Gloucestershire Royal Hospital.

The boys fell at the former Premiere Products building in Bouncers Lane, Prestbury, Cheltenham, at around 1.30pm yesterday.

It is understood that they had been seen taking photos from the top of one of the buildings in a derelict compound.

Injuries have been described as serious by police.

A Gloucestershire police spokesman said they were called to the scene, near to the crematorium and cemetery, at 1.34pm.

He said: "There were reports of two people who had fallen through a roof at the former Premiere Products site.

"Because of the nature of the incident we sent a lot of resources to the scene, it was a quite substantial response."

Gloucestershire Fire and Rescue Service said it was called to the scene to help police and ambulance gain entry to the compound. Both teenagers were taken to hospital.
