A gay couple were subjected to a torrent of offensive anti-gay abuse on a London Overground train earlier this month.
The incident happened just before 6pm on the 17:38 Hampstead Heath to Stratford service on Saturday October 1st.
According to British Transport Police, the male couple were sitting in the first carriage close to another man, who began making rude and inappropriate remarks.
The abuse became worse and the couple left the train at Canonbury and called police. Their abuser remained on the train.
PC Ian Russell, the investigating officer, said
: “This type of behaviour is offensive and intimidating and has no place on the rail network.
“Homophobic abuse will simply not be tolerated and I am determined to bring the person responsible to account.
“I am now urging anyone with information to contact police.”
The man police would like to identify is described as black, aged between 27 and 35 years, of a stocky build with short black hair. He was wearing a blue polo-shirt and blue jeans.
Anyone with information can contact British Transport Police on 0800 40 50 40 or the independent charity Crimestoppers on 0800 555 111.
