A man suffered homophobic abuse on a train from Charing Cross to Bexleyheath.
British Transport Police (BTP) officers are appealing for information after the man suffered homophobic abuse and was assaulted on July 15.
Investigating officer, PC Michael Willoughby said: “The victim boarded the train at Charring Cross around 5.30am.
"During the journey a man sat opposite him and began making homophobic comments to him and began taking pictures of the victim on his phone.
“The victim challenged the man, but was punched and kicked in return.”
The suspect is described as Chinese man, aged around 35, wearing a casual dark grey shirt, black trousers and black shoes. He is thought to be of proportional build and around 5’9.
Officers are appealing to anyone who was on the service at the time and who may have information about what took place.
PC Willoughby continued: “Anti-social or violent behaviour has no place on the railway and passengers should feel able to use the network without fear of becoming a victim of crime.
“Anyone who witnessed the incident, or who has any information about what took place, should get in touch.”
Anyone with information should contact British Transport Police by calling 0800 40 50 40 or texting 61016 quoting SSUB/B6 of 7/8/14. Alternatively contact the independent charity, Crimestoppers, on 0800 555 111 anonymously.
