Police in London have evacuated the streets around one of London's busiest underground stations, amid reports of gunshots and panicked crowds.
The Metropolitan Police issued a statement saying they responded to an "incident" at the Oxford Circus station.
It added that the station was reopened within 90 minutes, as police had "not located any trace of suspects, evidence of shots fired or casualties".
An altercation between two men at the Oxford Circus tube station seemed to have sparked the event, leading to what has been reported as a "stampede" from the station, in which up to nine people may have been injured.
Chief Superintendent Martin Fry: "Thank you to everyone for bearing with us this evening and also to colleagues from all the emergency services who helped carry out a swift response".
Armed police were on the scene and are investigating the incident, according to witnesses.
Those who are not in the area should avoid travelling to Oxford Street.
