A Ryanair flight attendant and her girlfriend were beaten up on a London bus by a group of men after they refused to kiss for the gang of four thugs.
Melania Geymonat, 28, said the attack on her and girlfriend Chris happened on the top deck of a London night bus as they were travelling to Camden Town in the early hours of 30 May.
Geymonat, a Uruguayan, may have also suffered a broken nose during the violent attack after a night out in north London.
Scotland Yard is investigating.
Officers are "following up" on CCTV footage of the assault, a spokeswoman for the force said.
Ms Geymonat told BBC Radio 4's World at One she experienced "a lot of verbal violence all the time".
“I had a date with Chris,” Geymonat posted on her Facebook page. “We got on the Night Bus, climbed upstairs and took the front seats. We must have kissed or something because these guys came after us.”
