Trafalgar Square was closed off this afternoon after a suspicious package was found.
The square was evacuated, and the surrounding roads were closed off. People at the scene reported a heavy police presence as they surrounded the square and cordoned it off.
Many eyewitnesses said that a controlled explosion was taken out on a dustbin, which has now been confirmed by the Metropolitan Police.
Eyewitness Emma Divine told Blottr "[I] heard loud bang like gun shot but realised it must have been controlled explosion when we saw Trafalgar Square cordoned off".
Eyewitness Alex Smethurst, a student at LSE, told Blottr that a "controlled eposion on a package in Trafalgar Square led to police & streets blocked but offices were never evacuated."
Police refused to comment on the incident at Trafalgar Square but confirmed that there is a 'suspect package'.
At approximately 3.30pm the web cam showing Trafalgar Square showed the public re-entering the square with the police cordons removed.
