Two passenger cars have collided on the E18 just west of Arboga, the police write.
Before the collision, one of the car drivers is said to have fled from a police checkpoint.
The road has been closed in the direction of Örebro, and it is unclear when it can reopen.
The incident occurred shortly after ten o’clock on Friday afternoon.
According to the police, one of the car drivers, a man, must have tried to escape a police check before the collision.
– The motorist does not want to be checked. Then a pursuit begins at fairly high speeds, says police spokesperson Anders Dahlman.
After a short chase, the driver turned off the E18 at Arboga, and then went out on the road again in the direction of Örebro.
Road closed
After another moment of police pursuit, the car collided with another.
Traffic is heavily affected by the incident, and the road in the direction of Örebro has been closed.
The extent of the injuries is unclear, but both motorists are said to have been awake and able to speak.
The police do not yet want to comment on the man’s age or whether he is already known to the police.
