Police are investigating an attempted robbery after a gang of masked men targeted a lone biker at a set of traffic lights.

The victim, who was in his 40s, was waiting for the light to turn green at the junction of New Road and Heathway in Dagenham when he was approached by the group of six assailants shortly before 8.45am on Wednesday.

Three of the men tried to take his bike. When he resisted, one of the group slashed his jacket with a knife.

Nearby road users shouted at the offenders when they realised what was happening, and the three men ran off and joined the rest of the group who were standing in Goresbrook Road. All wore face coverings and gloves.

London Ambulance Service were called and treated the victim but no injuries were reported.

No arrests have been made. Enquiries continue.
