An explosion was reported from a carriage of a London Tube train on Friday, causing injuries as panicky passengers tried to escape from the scene, witnesses and officials said.
The Metropolitan and British Transport police forces were at the scene at Parsons Green station in south-west London, the Guardian reported. But no one could provide further details on what happened.
Transport for London tweeted: "We are investigating an incident at Parsons Green." Train services between Earl's Court and Wimbledon on the District Line were suspended.
A witness told the daily that there were injuries at the station after a stampede.
A picture on social media showed a white bucket inside a supermarket bag, but did not appear to suggest extensive damage in the carriage, reports the BBC.
A BBC London Correspondent who was at Parsons Green on her way in to work said: "There was panic as people rushed from the train, hearing what appeared to be an explosion... People were left with cuts and grazes from trying to flee the scene."
