A 15-year-old boy has been found guilty of a barn arson which caused damage valued at £155,000.

The teenager, who had denied the offence at Walton Stables in High Road, Trimley St Mary, will now face sentencing with a 14-year-old girl and another 15-year-old boy who admitted arson before the trial at Ipswich Youth Court.

The trio will be sentenced on May 2.

A fourth youth – a 14-year-old boy accused of arson had the case against him dismissed during the trial.

The fire occurred on July 4 last year at around 6pm.

The blaze was said to have been started by igniting a PE top using a deodorant as a makeshift blowtorch.

The fire spread after the aerosol canister of deodorant had been thrown on to the fire. An attempt to kick it off caused the fire to burn brighter.

The barn was destroyed and had only been insured for demolition.

Bidwells - which looks after the property for the owner Trinity College Cambridge - said the total cost of the damage is valued at £155,000.
