London terrorism threat police operation begins Published duration 8 June 2014

A drive to remind people in London of the "ongoing threat from terrorism" has started.

Operation Griffin, involving Scotland Yard, City of London Police and British Transport Police will brief and remind the public to stay vigilant.

The operation will include automatic number plate recognition and high-visibility patrols across all 32 boroughs until 15 June.

Cdr Simon Bray said: "The threat to London from terrorism remains real."

As part of the operation, briefings will also be held for officers in each borough to ensure continuity between national and neighbourhood policing.
