Pair arrested over stabbing death

Police said a drink was thrown before Mr Bigby was stabbed

Two teenagers have been arrested by police investigating the fatal stabbing of a man in London's West End.

Steven Bigby, 22, was stabbed in the chest soon after leaving a McDonald's restaurant on Oxford Street with friends on Monday afternoon.

Detectives arrested the two aged 18 and 19 in connection with the killing.

Police said Mr Bigby died after two groups clashed in a "spontaneous incident". A knife has been recovered from the scene.

A post-mortem examination showed the victim died from a single stab wound to the heart.

Rape trial

Mr Bigby was one of 10 defendants charged with the rape of a 16-year-old girl and causing grievous bodily harm, the Crown Prosecution Service (CPS) has confirmed.

The teenage girl was attacked in north London in January.

In a separate case, he was due to go on trial in June for wounding with intent and violent disorder, over a stabbing in October 2006 in north London, the CPS said.

Earlier, police revealed a row had broken out in McDonald's during which a drink was thrown.

Det Ch Insp Bob Mahoney said: "The incident escalated very quickly and Steven was fatally stabbed.

"At the moment we are treating it as a spontaneous incident.

"There is nothing to suggest that this is a gang-related crime or linked to any other incidents."

Mr Mahoney also appealed to witnesses who took photographs of the incident to come forward.

The teenagers arrested on Tuesday are being questioned at an east London police station.
