Police are appealing for witnesses after a man was punched in the face on a bus.

The victim, a man in his 40s, was on the Route 18 bus in Wembley heading towards Sudbury on July 9 at around 7.40pm when he was attacked.

According to the Met, the bus stopped at Flamsted Avenue when another man boarded the bus and punched the victim in the face.

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

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