Arrest after small explosion metro London

The police in London have arrested a 23-year-old man in connection with the small explosion Tuesday in a subway station in the north of the British capital.

The police, who do not speak of terror, think that the explosion in the Southgate station was caused by a battery of a drilling machine. Eyewitnesses spoke of a rubbery smell and flames nearly two meters high.

Five people were injured. Two of them were taken to the hospital.
