Police have launched an appeal after a man was bitten on the ear by a fellow train passenger.
The victim was on board the 11.40pm Southern Trains service between London Bridge and Peckham Rye on Friday 6 October with his friend.
Another passenger became annoyed that the victim's friend was speaking loudly on his phone and complained to them. A verbal altercation ensued, during which the passenger leaned over and bit the victim's ear.
When the offender eventually stopped biting the victim's ear, he went and sat back down in his seat.
The victim and his friend left the train at Peckham Rye.
He sustained a deep cut to his ear (above) and required hospital treatment.
Officers have been making enquiries since the incident occurred and would now like to speak to the man shown in the CCTV image (below) as he may have information which could help the investigation.
If you recognise him, call BTP on 0800 40 50 40 or text 61016, quoting reference number 376 – 08/10/2017.
