The gang leader Ismail Abdo, known as "Jordgubben", is suspected of being involved in a murder attempt in Malmö in the summer of 2024.
He was requested to be detained in his absence, but the district court rejected the prosecutor's request, writes SVT.
It was in August last year that a 25-year-old man was shot and taken to hospital with serious injuries. A 13-year-old boy was arrested shortly after the shooting and was handed over to social authorities.
Ismail Abdo is one of Sweden's most wanted criminals and just over a week ago, he was detained in his absence for aggravated drug offenses.
Abdo, who is believed to be staying in Turkey, where he is also a citizen, previously had close ties to Foxtrot leader Rawa Majid, but they are now on opposite sides after a violent conflict that broke out in the fall of 2023.
