An investigation has been launched after a passenger's hand became trapped in the closing doors of an Elizabeth line train as it was leaving London's Ealing Broadway station.
The incident, which happened shortly after midnight on 24 November, saw the passenger having to run alongside the train before they were freed by a member of staff who was working on the platform.
The driver was alerted to what was happening by other rail users, and the train stopped after moving approximately 17m (56 ft). The passenger reportedly suffered minor injuries.
The Rail Accident Investigation Branch (RAIB) said it would look into what happened. Transport for London has been approached for comment.
