A distraught Hounslow mum has delivered a stark warning to teenage tear-aways after her son ended up in intensive care while seemingly trying to steal lead from a roof.

Jackie Knight says her son Adam and a group of friends were attempting to scale the roof of an empty warehouse in Isleworth when he lost his footing and fell.

Jackie, of Cromwell Road, has now released pictures of her 17-year-old son in his hospital bed in the hope that it will discourage other young people from engaging in the dangerous and illegal activity.

Adam suffered a fractured skull, a broken eardrum, a fractured wrist and a fractured pelvis after falling 45ft through a window on the roof of the old SITA telecommunications building, in Clock Tower Road, on July 21.

Mum-of-five Jackie told the Chronicle: "I thought he was going to die, he is so lucky to be alive."

The 48-year-old said her son admits he and the group went to the building to steal lead and copper but has no recollection of the actual accident.

"I want this picture to be a wake-up call

to other young people who are doing the same things as Adam, I want them to see what can happen," she said.

"I also want it to be a wake-up call for him. He has been doing nothing with his life since leaving Whitton Community College, he needs to get a job."

After the accident, Adam was taken by a friend's parent to West Middlesex Hospital, where paramedics immediately administered pain relief and placed him in the intensive care unit.

He has since regained consciousness but

had no feeling in one side of his face, due to nerve damage, and was being transferred to Charing Cross Hospital in Hammersmith for an operation as the Chronicle went to press.

A spokesman for Hounslow Police said it was aware of the incident but no arrests had been made or charges brought against any of the group because of lack of evidence.

"It is very difficult to prove anything was stolen as it is a very old building and so hard to tell what state the roof was in before," he added.
