Hundreds have been evacuated from Oxford Circus tube station amid reports of gunshots at the tube station and on Oxford Street.
Armed police have arrived on scene and are responding ‘as if the incident is terrorist related’ after reports of shots fired.
Hundreds of terrified shoppers who had flocked to the street on the one of the busiest days of the year fled the streets as police forced everyone into stores.

He left the scene and is unsure what is happening now but said armed police are still heading towards the station.
