Four teenagers have been arrested over a homophobic attack on a lesbian couple after they refused to kiss while travelling on a London night bus.

The four males, aged between 15 and 18 years old, were arrested today on suspicion of aggravated GBH and robbery.

They have been taken to police stations for questioning, Scotland Yard said.

Melania Geymonat, a 28-year-old air hostess, and her girlfriend Chris were left bloodied and in shock after the attack on May 30 that she said started when the men asked the pair to kiss for their entertainment.

Ms Geymonat shared a photo in a Facebook post of her and Chris on the N31 bus, which they had been taking from West Hampstead to Camden, with their faces and clothes covered in blood.

A group of young men began harassing the two women, who were sat on the top deck of the bus, when they discovered they were a couple, asking them to kiss while making sexual gestures.

Ms Geymonat said the gang behaved like "hooligans", throwing money at the couple before punching them in an attack which left them covered in blood.

Both women were taken to hospital for treatment to facial injuries.

Ms Geymonat added that the gang may have broken her nose during the ordeal, and stole a phone and bag before fleeing.

She said one of the men spoke Spanish and the others had British accents.

Detective Superintendent Andy Cox labelled the attack "disgusting".

He said: “The suspects have made a number of homophobic comments towards the couple before throwing coins at them. When the women tried to reason with the group, the attack escalated to an assault.

“CCTV footage from the attack is being reviewed by detectives. We continue to appeal for information from the public, particularly those who were present on the bus before or after the attack to come forward and tell police what they saw.”

DS Cox said officers were still attempting to “trace other individuals suspected to have been involved in the incident", adding: "Lots of people will understandably be outraged by this attack.”

"Our efforts to trace all the suspects involved and bring them in for questioning will be relentless," he said.

Prime Minister Theresa May, Labour leader Jeremy Corbyn and London mayor Sadiq Khan all condemned the attack.

Mrs May said: "This was a sickening attack and my thoughts are with the couple affected.

"Nobody should ever have to hide who they are or who they love and we must work together to eradicate unacceptable violence towards the LGBT community."

Mr Corbyn said: "We must not, and will not, accept this homophobic and misogynist violence in our society.

"Solidarity to Melania and Chris, and to all in the LGBT+ community for everything they endure for simply being who they are."

London mayor Sadiq Khan added: "This was a disgusting, misogynistic attack. Hate crimes against the LGBT+ community will not be tolerated in London."
