London’s Trafalgar Square was briefly evacuated by police on Saturday following a report of a suspicious car.
It comes as London enters the third day of events to celebrate Queen Elizabeth II’s Platinum Jubilee.
Shortly after the evacuation, Police removed the car and said the incident was not terrorism-related.
The iconic central London square is less than a mile from Buckingham Palace, where the queen resides and where a concert is to be staged on Saturday evening.
The force said at 11:06 a.m. that officers had evacuated the scene and asked people not to travel to the area.
Ten minutes later, it said the incident had been concluded and the square was to reopen in due course.
A police car transporter was seen at the scene carrying a car.
Police said officers have “no further concern” after investigating the incident, which it said “was not terrorism related.”
“We encourage everyone to share with police any concerns they might have whilst out and about. Please remain vigilant,” the police added.
A police spokesman said earlier that the force was carrying out many checks in the area.
At 7:40 p.m. on Saturday, the BBC’s Platinum Party at the Palace concert is due to take place at Buckingham Palace as part of the celebrations to mark the queen’s record-breaking 70-year reign.
The queen’s son and grandson, potential future kings Prince Charles and Prince William are expected to pay tribute to the queen during the star-studded open-air concert.
The four-day jubilee festival started on Thursday, which was also the 69th anniversary of the coronation of Elizabeth, who became queen on the death of her father George VI in February 1952 and is head of state of 14 other countries including Australia, Canada, and New Zealand.
She has now been on the throne for longer than any of her predecessors in 1,000 years and is the third-longest reigning monarch ever of a sovereign state. Opinion polls show she remains hugely popular and respected among British people.
