The busy tube station was fully closed this evening, as a man was believed to be making threats to members of the public.
Videos from the scene show a number of police officers running from a van and heading down into the underground station.
Officers then blocked people from entering the station.
An eyewitness said: “Five or six police officers were wrestling the man as he shouted. They were wrestling him into an ambulance. Surely if they were doing that it should be a police car.”
Another person at the scene said they saw a man being led up the steps by police.
