A teenager from Tooting is among four boys who have denied harassing two women in a homophobically aggravated attack after they refused to perform a sex act on a bus.

Two 17-year-olds, a 16-year-old and another boy, 15, appeared at Highbury Corner Youth Court in London on Wednesday to enter not guilty pleas to a charge of causing harassment by using threatening or abusive words or behaviour.

Melania Geymonat, 28, and her girlfriend Christine Hannigan were allegedly targeted by the four teenagers in the early hours of May 30 on the top of a double-decker bus in Camden.

The court heard the boys moved from the back of the bus to surround the women and began making sexual gestures.

During the incident shortly after 2.15am, the boys are said to have demanded they kiss and perform sexual acts.

After the women refused, the four boys then were said to have thrown coins at the women.

Both women were taken to hospital with facial injuries after the alleged incident.

The 16-year-old, from Tooting, admitted stealing Ms Geymonat's handbag during the alleged attack but denied handling Ms Hannigan's stolen Google Pixel mobile phone.

The 15-year-old, from Kensington and Chelsea, also denied handling Ms Geymonat's stolen bank card.

Both 17-year-olds are also from Kensington and Chelsea and one denied possession of cannabis.

The four boys will appear again at Highbury Corner Youth Court for a two-day trial starting on November 28.

Both of the women and the bus driver are expected to give evidence
