Overweight teenagers in South Yorkshire could be fitted with gastric balloons, if a trial is approved.

Sheffield Children's Hospital said it wanted to use the balloons to help 10 morbidly obese 13 to 18-year-olds lose weight.

Those weighing between 14 and 20 stone (89kg-127kg) will be considered.

Dr Neil Wright from the hospital said the procedure was "intended as an option for young people where other treatments have not been successful".

The hospital said the procedure had been found to be effective for adults but very few studies had been carried out on young people.

The gastric balloon discourages overeating by inflating in the stomach to give the feeling of being full.

Plans for mandatory custodial sentences for 16 and 17-year-olds who threaten others with knives have been unveiled by Justice Secretary Kenneth Clarke.

Convicted teenagers would face a four-month detention and training order.

The proposals form part of a new sentencing regime for the courts.

Also planned is a "two strikes and you're out" policy which would see a person convicted of a second very serious sexual or violent crime get a mandatory life sentence.
