A MOTHER today told how her son feared he was paralysed after falling 30ft from the roof of a derelict building.

Mandy Frankland, of Stanley Street, Accrington, is now warning other youngsters to stay away from building sites during the school summer holidays.

Her son, 11-year-old Jake, and an 11-year-old pal climbed on to the former Broughton Crangrove mill on Tuesday evening.

The Paradise Street mill is due to be demolished in two weeks' time to make way for a state-of-the-art health centre.

The derelict old mill is currently boarded up to prevent members of the public gaining access.

Jake fell through a plastic lighting panel in the roof of the disused building and was knocked unconscious when he landed on the concrete floor below.

Mrs Frankland said: "He was supposed to be at youth club, but the pair of them wandered off and then decided to go clambering on the roof and Jake fell through.

"When he came to, he thought he was paralysed because he couldn't move.

"He was very frightened, but fortunately the feeling in his arms and legs started to come back.

"I received a call from the police about half-an-hour after it happened and I rushed down to the hospital. It was every parent's worst nightmare."

His friend used his mobile phone to call for an ambulance.

Mrs Frankland added: "Both of the boys were very brave in dealing with what happened, although I think they are still very shaken by it now. A lady police officer dropped through the roof on a rope to keep Jake company while he waited for the ambulance."

Jake was kept in the Royal Blackburn Hospital overnight and was lucky to survive the plunge with only a broken wrist, but his mum said that has been more than enough to teach him a lesson about building sites. She added: "I will wait to have a word with him when he's feeling a bit better, but I think he has put himself off already. He says he definitely won't be climbing on any roofs again.

"Jake's accident should serve as a warning to other kids about playing on building sites, because they are dangerous places. I am glad to have Jake back home now, in almost one piece, but other children may not be so lucky."
