Police are appealing for information after a teenager dressed as a penguin was assaulted on board a train.
The 19-year-old was travelling with his dad, aged 56, on a train from Liverpool Street to Chelmsford between 11.50pm and 12.25am on December 21.
A group of six other men asked the 19-year-old, who was waiting outside the toilet, if he supported Tottenham.
After using the toilet the teenager, who was dressed in a penguin fancy dress costume, found the men blocking his way and being aggressive.
His dad then tried to pull him away but both were punched and kicked. The disorder spilled out onto the platform at Chelmsford, and a passer-by who intervened was also assaulted and sustained a black eye.
Police believe the people pictured as they may have informaton which could help the investigation.
Anyone who recognises the men or witnessed the attack should call 0800 405040 or text 61016, quoting reference number 228 of January 9, 2018.
