It was at 6 pm on Wednesday that several police patrols pulled out towards Årby after alarms about loud bangs.
Police said on Thursday that the investigation shows a dramatic incident where a car drove at full speed over a lawn with a view of a person, who escaped and then fired shots at the car.
- These are thus two different cases of attempted murder, says Christoffer Bohman, head of the investigation section in the Södermanland police area.
The three who were traveling in the car were arrested later in the evening.
All three are suspected of attempted murder, but one of them is primarily suspected of the attempted murder and the shooting in the center of Årby on 13 March.
The fourth person, ie the target for the collision, is still wanted by the police and he is also suspected of attempted murder.
