The Norwegian police believe that they drove Lars Thorsens, the leader of the anti-Islamic group Stop the Islamization of Norway (Sian), a car on purpose.
In the Sian car, which ended up upside down when it was hit by the road, there were five people in total.
According to NRK, no one is seriously injured.
The woman who was driving the other car was arrested on Saturday, on suspicion of causing grievous bodily harm and for intentionally causing the collision.
On Sunday, the police announced that the fellow passenger had also been arrested.
