It was in mid-March that a 16-year-old boy was in the parking lot at the NHC arena in Timrå with his friends.
When the boy's friends were a short distance away, a group of teenage boys allegedly confronted the 16-year-old and then started beating and kicking him.
When he tried to get out of the place, they must have followed and jumped on him from behind.
- The whole gang then started kicking and hitting me when I lay down.
I was lying on the side of my body and pulled my legs up towards my chest and I tried to protect my head with my arms and hands, he states in interrogation.
The 16-year-old's friends must then have understood the situation and helped him.
Four films showing the assault were spread later that evening on Snapchat by one of the suspects.
Four of the five teenagers admit involvement in the incident.
The fifth denies the crime.
