Two people who confronted a gang vaping on the train were savagely attacked, leaving one with a broken cheekbone and the other with hair torn out.
British Transport Police today released images of four people they’d like to speak to in connection with the attack, which happened on board a Brighton train on 19 July.
After the two victims asked the group to stop, the vapers became first verbally and then physically abusive.
The incident took place as the train was travelling past Gatwick Airport.
Officers believe the people in the CCTV images may have information which could help their investigation.
