The incident took place last spring, when three 15-year-old boys were out in central Stockholm celebrating a birthday.
After being rushed home, they started running towards the bus and are said to have been jumped on by four men dressed in black who later turned out to be civil police.
According to interrogations, one of the boys must have been wrestled down by the men.
One of them is said to have been kicked in the stomach and then forced to undress in the middle of the street, when the men wanted to search his clothes.
- It was unpleasant because there were a lot of people who passed by and they also laughed at the same time when they saw me completely naked, says the boy in questioning.
Drove the boys home
According to the police, they had received an alarm about an assault in an adjacent street when they saw the boys "running and behaving strangely".
In questioning, one of the policemen says that they resorted to violence after the boys allegedly tried to escape.
When the police later realize that the boys are innocent, they should have given them a ride home.
After finding out what happened, the police were notified by the boys' parents.
May lose job
One of the police officers is now charged with assault and misconduct.
The prosecutor considers the actions of the other police officers to be within the police's powers.
The accused police officer will be fired from his post if he is convicted of non-minor assault.
