Moment machine gun-toting police grab three suspects on London Tube platform in dramatic

Machine gun-toting police grabbed three suspects on a London Tube platform in a dramatic arrest in front of terrified passengers.

Armed officers could be seen swarming the platform of St James’s Park Station in the capital’s bustling West End. 

All seemed normal at the popular District and Circle Line station until a series of loud shouts were heard as the cops – dressed in all black and wielding machine guns with attached torches – descended on the station.

Video taken from the opposite platform shows one suspect standing against the wall and raising his hands before being dragged to the ground by an officer.

The other two were seated on a bench before being forced to the floor in full view of stunned London Underground customers. 

Between them, the four officers pin the suspects on the floor while aiming their weapons at them and shouting. 

Once the three suspects are laying still on the ground, three more police attend the scene.

While some bystanders watched on with interest, others gathered themselves together and slowly moved away from the action. 

St James’s Park is one of London’s busiest Tube stations, servicing around 13.5million passengers a year and situated close to major attractions including Buckingham Palace.

The Daily Mail has approached the Metropolitan Police for comment.
