A mother has made a desperate plea for help with her uncontrollable 11-year-old son.

Lisa Gedling's son Alex has already been expelled from two primary schools and the city's specialist Alternative Centre for Education (ACE) because of his extreme violent behaviour.

On a series of occasions he punched and kicked fellow pupils and teachers at West Hove Infants and Goldstone Primary, threw chairs at people and clambered onto the roof.

Mrs Gedling, of Wickhurst Road, Portslade, said Alex had a combination of severe autististic conditions which made it impossible for him to control his temper and meant he has no understanding of how he is hurting others.

He is currently being taught at autism specialist Patcham House School, in Old London Road, Brighton, but even there staff refuse to let him be around other children, instead allowing him in for only one hour a day outside of normal school hours.

For the rest of the day Mrs Gedling has to look after him at home and even she cannot control him. He repeatedly attacks her and her other children Reece, 16, and Phoebe, 5.

She said he would get into a violent rage up to 50 times a day and she regularly had to call her partner to come back from work to help. He has now be warned by his employers.

Mrs Gedling said: "It has got to a desperate stage now and we don't know where to turn. He is already too strong for me to restrain him and he is only 11. I'm worried about what will happen as he gets older."

She has pleaded with Brighton and Hove City Council to fund a place for Alex at a residential school where specialists will be able to give him the 24-hour support.

She said: "There isn't really anything else we can try."

At the moment the council has told her it cannot meet the cost.

A council spokesman said children's services staff were trying to help the family.

He said: "We will continue to work with the child's parents to resolve these issues. A multi-agency meeting is planned to review the educational provision for his special educational needs, and to consider what provision is required to ensure his educational and social needs are being fully met."
