The child has been taken to hospital by ambulance. The extent of his injuries is unclear.
The woman is suspected of gross negligence in traffic, causing bodily harm and evading a traffic accident.
We have started talking to some witnesses, we will talk to the woman who has been arrested and in the future we will also talk to the child, says police spokesperson Angelica Israelsson Silfver.
The woman was arrested a few streets away from where the collision occurred.
The problem is that she did not stop at the accident itself, but continued driving. Then we'll see if we can get an explanation for why," says Israelsson Silfver.
The car has been seized.
