Armed police evacuated Bond Street tube and five people were arrested after a suspected robbery involving a gun.
The station was closed at about 8.30pm on Friday after a man told police he was robbed in nearby Oxford Street by suspects with “a firearm and a knife”.
The Metropolitan Police said on Twitter: “Officers have arrested five people at Bond Street Underground Station following reports that a man was robbed on Oxford Street. The station was temporarily closed.”
The station reopened at about 9.50pm.
A police spokeswoman said: “Officers attended and spoke with the male victim. He informed officers that the suspects were in possession of a firearm and a knife, and that they were last seen entering Bond Street Underground Station.
“Officers, including firearms officers and British Transport Police, are in attendance.”
Transport for London said there were severe delays on the Central Line after the station shut down.
The official Central Line Twitter account warned customers to avoid using the line, adding: “The delays are due to a customer incident at Bond Street.”
