A man's ear was bitten when a train row erupted over a person's loud mobile phone conversation, police say.
The 24-year-old victim was bitten after another passenger complained about his friend "speaking loudly on his phone" on the London commuter route late on Friday 6 October, according to the Daily Telegraph UK.
"A verbal altercation ensued, during which the passenger leaned over and bit the victim's ear," British Transport Police (BTP) said.
"When the offender eventually stopped biting the victim's ear, he went and sat back down in his seat.
