Scotland Yard is investigating a suspected gunshot that hit the back window of a taxi containing the Private Eye editor, Ian Hislop.

The black-cab driver told detectives he had come to a standstill in traffic in Soho, central London, just after 10am on Tuesday morning when he heard what he believed was a bullet hitting and damaging his window.

Both the driver and Hislop, who was in the rear of the cab, escaped without injury.
