A cleaner has been arrested after apparently stealing a train before it crashed at high speed into a house in Sweden.
The woman was seriously injured when the train derailed at Saltsjobaden station, southeast of Stockholm, and collided with the building, said police spokesman Lars Bystrom.
She was flown to hospital in the capital city and has been arrested on suspicion of endangering the public.
The cleaner allegedly stole the four-carriage train at a depot then drove it around a mile (1.6km) before it crashed, a spokesman for train operator Arriva said.
Witnesses said the train did not slow down when it reached the station before smashing through the stop barriers at the end of the track.
No-one in the house, which sits around 50 metres from the stop barriers, was injured and there were no passengers on board the train at the time.
