Football fans were on-board a District line service travelling back from a football fixture at Chelsea FC's home-ground, Stamford Bridge on the 23rd.
As the service approached Earl’s Court Underground station a fight broke out between two groups.
A man then ran down the carriage and began attacking the victim near the train’s exit doors.
The attack continued on the station’s platform and the victim was punched to the floor.
As the victim lay on the floor, the man kicked him in the face.
The victim suffered a broken nose and lost two teeth as a result of the attack.
Officers believe the man in the CCTV footage may have information which could help their investigation.
