Friday 13th at London Bridge Station: zombies, police and snappers

The plan was that 'zombies' should turn up on the main concourse at the station with Michael Jackson's Thriller on their music players.

On the stroke of 7pm they were to break into a zombie dance for exactly three minutes.

The British Transport Police weren't taking any chances with the event after last week's flashmob at Liverpool Street led to the temporary closure of that station.

There was a heavy police presence and would-be zombies were redirected to the bus station outside the concourse where there was no visible clock for participants to coordinate their actions.

Earlier the organisers had pulled the plug on a Facebook event listing for the flashmob in a bid to keep numbers down after British Transport Police and Network Rail expressed concern about the stunt.

Organiser Greg Tallent – a lecturer at London South Bank University – admitted on Twitter that the event "didn't quite work as expected" but added: "We did have fun, though."

The main London Bridge Festival – an open-access arts festival – takes place from 10 to 25 July. Full details at www.londonbridgefestival.com
