A police operation in the Oxford Street area of London has been stood down.
Police were called just after 4.30pm with numerous reports of shots fired in a number of locations on Oxford Street and at Oxford Circus underground station.
The Metropolitan Police say given the nature of the information received, it responded in line with its "existing operation as if the incident was terrorism" - including the deployment of armed officers.
Officers working with colleagues from British Transport Police carried out an urgent search of the area.
Police say "no causalities, evidence of any shots fired or any suspects" were found by police.

It adds that people who sought shelter in a building can now leave and follow the direction of police officers on the ground if they need assistance.
Both Oxford Circus and Bond Street stations were closed for a time, but have since fully re-opened.
The transport body Transport for London (TfL) said earlier the operation was due to a "customer incident".
Oxford Circus Station is closed while we investigate a customer incident. All trains are not stopping and paper tickets will be accepted on local buses
