A teenager was jailed for possessing a firearm yesterday.

The 17-year-old from Chingford was sentenced to three years in prison at Snaresbrook Crown Court after police caught him with a sawn-off shotgun and two cartridges on November 16.

The boy was watched by police as he walked into Goldsmith Road, Leyton, carrying a black and white holdall which contained the weapon at 10.10pm that day.

He then got into a minicab which was followed by detectives from the anti-gang Trident task force, who had been tipped off about the weapon pick up.

The detectives pulled the minicab over in Palmerston Road, Walthamstow, and also found a 19-year-old in the front passenger seat and a 16-year-old in the rear, next to the holdall.

All three were arrested, and police discovered that the minicab had been sent to the Chingford Hall estate to pick up the trio, before heading to Goldsmith Road.

The 17-year-old pleaded guilty to possessing a firearm and his barrister said he had collected the weapon to repay a debt  of £200 to someone.

The two other teenagers arrested are currently on police bail.

None of the teenagers can be named due to legal reasons.

Detective Constable Neil Whitbread of the Trident Gang Crime Command said: "This case illustrates how successfully Trident can detect and prosecute those prepared to transport weapons across the capital.

"Anyone with information on firearms crime is asked to contact police on 101; if you wish to remain anonymous call Crimestoppers on 0800 555 111."
