Update: Arrests of 3 teens in London gay man's slaying

Police hunting for the killers of a 62-year-old gay man who was beaten to death in Trafalgar Square have arrested two 17-year-old girls and one 18-year-old boy.

Ian Baynham was attacked on September 25th. After suffering brain damage, his life support machine was switched off on Tuesday.

According to a Metropolitan Police spokesman, the girls were arrested at their homes in south-east London, as was the 18-year-old male.

They are being held at separate police stations and will be questioned.

Baynham was out celebrating a new job with a friend when the attack happened. The teenagers had reportedly been shouting obscenities at passerbys when he confronted them over their behaviour.
