Another child is suspected of involvement in the murder in Södertälje last week, which Länstidningen Södertälje was the first to report.
Last week, a man in his 20s was found seriously shot in the Blombacka area of Södertälje. He later died of his injuries.
A person who had been detained on reasonable suspicion of aiding and abetting the murder was released on Thursday. Another person, under 15 years old, is still suspected of involvement in the murder.
The investigation is still in the collection phase with interrogations, review of surveillance footage, and forensic examination.
Three people are suspected of aiding and abetting. We are still looking for suspected perpetrators and I still have good hope that we will be able to prosecute those responsible for this act, says Mikael Carlsson to TT.
After the murder, the police announced that a security zone would be introduced in parts of Södertälje. It applies between July 6 and 19 in Västra Blombacka and parts of Geneta.
