A controlled explosion has been conducted outside 30 St Mary Axe (the Gherkin) in London’s insurance district, The Guardian reports.

The area was evacuated as office workers shared pictures and videos (below) on social media of a bomb disposal robot investigating a silver Ford Focus parked in the street.

Road closures have now been lifted and the driver has been arrested for possession of false identity documents.

City of London Police have said that officers attended the scene after an 11:32am report of a suspicious vehicle outside the building, but have not confirmed that the explosion took place.
