Attack At Portsmouth Harbour Train Station
Police are trying to track down three men after a big fight at Portsmouth Harbour train station - which left a man badly injured.
Police have released CCTV images of three men they would like to speak to in connection with an incident, which happened on Monday, 23 July.
Detective Constable Phil Bibbings, the investigating officer, said: "Around 9.20pm, heated words were exchanged at the front of the station between a group of youths and two brothers who were returning from a birthday party with their mother.
"Upon reaching platform 1, a fight broke out between the two groups, leaving the brothers, age 21 and 26, injured.
"One of the men suffered a fractured eye socket, broken nose and cheekbones, and the other received cuts and bruising to the face."
Following the incident, two men, aged 18 and 17, both from Portsmouth, were arrested on suspicion of GBH and ABH. They have been released on police bail due to return on Tuesday, 25 September.
Detectives are continuing their enquiries and have now released images of three other men who they would like to speak to in connection with the incident.
DC Bibbings added: "We have identified three men, who we believe to be from the local area, that we would like to speak to about the incident as we believe they hold key information.
"I would urge anyone who recognises the men, or knows their whereabouts, to get in touch."
