British police on Saturday briefly evacuated London's Trafalgar Square, close to where celebrations are to be held later to mark Queen Elizabeth's Platinum Jubilee.
Police said it followed reports of a suspicious vehicle, but the security alert had now concluded.
"This was investigated and after police took action we have no further concern. This was not terrorism-related," police said on Twitter.
A police spokesman said earlier that lots of checks were being carried out in the area, a short distance from where a concert is to be staged outside Buckingham Palace later in the day.
Police attended a report from a member of the public at 09:22hrs of a suspicious vehicle in Trafalgar Square.
