A 23-year-old man has been arrested after an explosion at a north London Tube station left five people injured.
Witnesses described smelling “burning rubber” and seeing “six-foot flames” at the entrance to Southgate Underground station in Enfield on Tuesday evening.
Police believe the explosion was caused by a faulty drill battery.
The man was held on suspicion of an act likely to cause an explosion to injure or damage property, and endangering safety on the railway. The station was shut and a cordon set up after the explosion occurred at about 19:00 BST.
London Ambulance Service said they treated three people at the scene for minor injuries while two others were taken to hospital.
