A 15-year-old boy was arrested last night on suspicion of possession of a firearm following a stabbing in Elm Park.

Police were called at 9.10pm to Calbourne Avenue to reports of a robbery of three men in their twenties involving a firearm and a knife.

A 21-year-old man was stabbed in the hand on the platform at Elm Park station and was taken to an east London hospital.

What is thought to be a replica firearm was recovered in a garden nearby.

The station was also closed for several hours as police carried out their enquiries last night.
