A British teen hanged himself on vacation after another youth made a disparaging comment about gay people, an inquest has found.

Nineteen-year-old Harry Corbett, who identified as bisexual, died in May while traveling with friends on a trip around the world during his gap year. According to reports, Corbett was having difficulties with one of the other boys. Mark Catley-Day says their dispute began in Australia, when the two got into a fight that turned physical.

“I made a gay-related comment to him and I think he got upset,” said Catley-Day

Tensions remained high and after another argument on a cruise in Vietnam Corbett reportedly said, “Tell my mum I love her,” before leaving the room. Ten minutes later, his body was discovered on the ship’s upper deck.
