“We naturally feel a certain relief over having come this far in a short time,” regional police chief Klas Johansson told media.
The suspect was described as a local 17-year-old who was previously known to police and according to prosecutor Ulrika Åberg belonged to a “conflict environment”.
The boy is suspected of murder and attempted murder with probable cause, but denies all charges. Åberg said she believed there were “more plaintiffs” for the suspicion of attempted murder.
Police have said they do not believe the police officer, who was in his early 30s and relatively new to the profession, was the intended target of the shooting.
The entire police force in the region has worked in various ways with the investigation, and help has also come from across the country, according to the police chief of staff Teodor Smedius.
“We have received fantastic support from the whole of the Swedish police. Everyone wants to help us. We have received the help we have asked for. We have also received great support from other authorities,” he told the TT news agency.
“The residents in the area have been cooperative and tell us what they’ve seen,” said Smedius.
Police have been conducting interviews, door knocking and searching technical evidence as part of the investigation that has been going on since the fatal shooting.
“This has been a terrible experience for us internally. We have to manage a balancing act; to take care of our staff and understand how this affects us as individuals,” Smedius said.
“At the same time, we must continue to work with full force. It requires security and it takes courage. It’s in our organisation and it’s amazing, in this tragic event, to see.”
