A woman was killed and three people were injured when a lorry ploughed into the side of a house in Barnsley.
Police were called to Park View, in Brierley, at about 13:40 BST, after the HGV crashed into the house.
A senior officer confirmed to the BBC the woman who died was a pedestrian. No details have been released about the injuries to the people who have been taken to hospital.
Police say four men have been arrested in connection with the incident.
Video footage has emerged which appears to show two young men getting out of the lorry before running away.
South Yorkshire Fire and Rescue said three fire engines, including one from West Yorkshire, were sent to the scene.
Park View is currently closed from the junction of Common Road and delays to bus services have been reported as a result of the crash.
