British police said they had arrested four teenagers on Friday after a gang of males beat up a lesbian couple who refused to kiss for them on a London night bus.
Melania Geymonat, 28, said she and her girlfriend Chris were left covered in blood after the attack last week.
"They started behaving like hooligans, demanding that we kissed so they could enjoy watching, calling us 'lesbians' and describing sexual positions," she wrote on Facebook.
"It was only them and us there. They kept on harassing us, throwing us coins. The next thing I know is that Chris is in the middle of the bus fighting with them. On an impulse, I went over there only to find her face bleeding and three of them beating her up. The next thing I know is I'm being punched."
"CCTV footage from the attack is being reviewed by detectives. Active enquires are in hand to trace other individuals suspected to have been involved. Attacks of this nature on London buses are rare."
