Police are appealing for information after a man was allegedly punched in the face on board a bus in Wembley.

The incident happened on board a route 18 bus heading to Sudbury as it stopped at Flamstead Avenue on July 9 at around 7.40pm.

Scotland Yard has released a CCTV image of a man they wish to speak to in connection with the incident.

The victim, a man in his 40s, made his way from the top deck to the back doors of the bus.

When the bus stopped at the Flamsted Avenue bus stop, a man boarded the bus and punched the victim in the face.

He then got off the bus and walked off towards Harlesden.

The victim required hospital treatment and was left with a severe cut and bruise.

Police Serg Craig Foster, from the Met’s roads and transport policing command, added: “This violent attack took place without any provocation. It was a shocking and needless use of force.

“Everyone should feel safe on our transport network and be able to travel without fear of an attack.

“If anyone has any information to help us identify this man, no matter how small, please do get in touch.”

Anyone who can help identify this man should tweet @MetCC or call 101 quoting reference CAD 6830/09Jul.
