A massive security alert in London, which caused dozens of anti-terror police-officers to be dispatched to probably the busiest street in London on Friday evening turned out to nothing.
Police have released images of two men they want to speak to. Police suspect they may have been involved in an altercation that created mass panic.
Officers want to speak to anyone who was at Oxford Circus underground station at the time of the evacuation.
Sixteen people were treated after they were injured fleeing the station, following reports of gunshots being fired on a Central Line platform.
There was no evidence any weapons had been fired, police said.
Shoppers were barricaded inside stores on Oxford Street and armed police were deployed after the alarm was raised during the evening rush hour on Black Friday.
Police initially treated the incident as potentially terrorism-related, before standing down.
The British Transport Police said it believes there was an altercation between two men on the platform before the scare.
