A driver is in a serious condition in hospital after crashing through level crossing barriers at Langworth near Lincoln during a police pursuit.
The crash, involving a Vauxhall Corsa, happened at around 2.30pm at the crossing on the A158.
The vehicle, believed to have been stolen, failed to stop for police before ploughing through the barriers and into a residential building.
A Royal Mail lorry is also understood to have been involved.
The road was closed while emergency services dealt with the scene.
Lincolnshire Police said just before 4pm that the driver had been airlifted to Queen’s Medical Centre in Nottingham with injuries described as serious.
Four other occupants of the car have been taken to hospital, but are said to have less serious injuries.
A Lincolnshire Police spokesperson said at 5.50pm: “Police were alerted to a Vauxhall Corsa in Lincolnshire which was believed to have been stolen in a neighbouring county.
“The Corsa had failed to stop for police when it was involved in the collision at the level crossing.
“Damage was caused to the barriers and a residential building. The collision did not involve a train.
“The crossing is currently closed. Motorists are asked to avoid the area if possible.”
The incident led to a number of disruptions on the rail line between Lincoln Central and Grimsby Town.
East Midlands Trains posted in a statement on their website at the time: “There are the emergency services dealing with an incident at Langworth Crossing, police were in pursuit of a car which has then gone through the barriers at the level crossing.
“This is between Grimsby Town and Lincoln Central. This is disrupting our trains on the Grimsby / Lincoln / Leicester route.”
