Police have found no evidence that a gunshot struck the back window of a taxi carrying the Private Eye editor Ian Hislop in Soho, after the driver reported it had been fired at.

An investigation was launched after the cab’s driver told the Met Police he was stuck in traffic when a suspected shot was fired towards his vehicle, striking the window just after 10am on Tuesday.

Providing an update on Wednesday afternoon the Met said: “Urgent CCTV and forensic examinations have been conducted. While enquiries are ongoing, police have found no evidence of a firearms discharge at this time.

“Initial indications suggest a mechanical fault might have caused the window to shatter. We await further tests.”
