Two separate bomb scares triggered evacuations in London but police later confirmed the threats were hoaxes.
A report of a suspicious vehicle near the British Broadcasting Corporation headquarters in central London caused panic as some reports said a part of the BBC building had to be evacuated.
The Metropolitan Police said the alert, which was soon over, was not specific to the BBC, and related to a vehicle parked on nearby Regent’s Street, ITV reported.
In another incident, people were forced to leave their offices when police evacuated buildings near the London Bridge station in a security alert. The area returned to normal after police sniffer dogs were brought in and a suspect package was checked, only to be cleared later.
BBC staff at the scene posted pictures of police cordons around the building, its headquarters in the capital.
London has been on an alert since the recent attacks in Paris that killed 130 people.
