Three people are wanted by police after a man was assaulted on a late-night Metropolitan Line train at Harrow-on-the-Hill station.

British Transport Police (BTP) have released CCTV images of three people they want to trace in connection with the assault which occured in the early hours of Sunday June 28.

The victim was heading home after a Saturday night out with friends and caught a westbound Metropolitan Line train from Baker Street station shortly after midnight.

During the journey, an altercation reportedly took place between the man and three other passengers, which led to a physical assault.

The victim was punched and kicked and his glasses were broken, BTP said.

The man ran from the train at Harrow-on-the-Hill station but was followed by the group and further assaulted on the platform.

He suffered a cut to his eyebrow and bruising to his face.

Police are now appealing for the public's assistance in identifying three people from CCTV images.
