The Met Police evacuated Trafalgar Square on Saturday morning after discovering a “suspicious vehicle”.
Pictures later showed a vehicle being removed from the scene although the Met said it was not terrorism-related.
Witnesses on social media said they were removed from the square amdi reports of a “loud bang”.
A large number of police officers were pictured at the scene while a cordon was also enforced.
The ambulance service said: "We are aware of this police incident but we haven’t been called."
Later, the Met said the incident had been resolved, with a spokesman adding: “Police attended a report from a member of the public at 09:22hrs of a suspicious vehicle in Trafalgar Square.
“This was investigated and after police took action we have no further concern. This was not terrorism-related.”
