Formal charged are expected to be filed against the man, who investigators believe may have been hired by the male victim’s ex-wife, by May 7th.

Police inspector Patrik Lilqvist, who is leading the investigation, thinks too much sensitive information has already been leaked from the investigation. As a result, Lilqvist is refusing to comment further on the case.

“We’re keeping it to ourselves,” he told the TT news agency.

Although the 41-year-old remains in detention, police and prosecutors are continuing their investigation on several fronts, said Lilqvist.

During the remand hearing, which took place at 2pm on Sunday, the 41-year-old contested the detention order. Defence attorney Peter Lindkvist claimed his client didn’t have anything to do with the case.

The court then grant a request by prosecutors that the remainder of the session continue behind closed doors.

The attack took place outside the Storkyrka School in Stockholm’s Old Town around 5.30pm on Tuesday.

The victims, a man and a woman both in their thirties, were hit be several bullets and remain at Karolinska University Hospital in stable condition.

The injured man’s ex-wife, a woman in her forties, was arrested shortly after the attack on suspicions that she hired a gunman to kill her former husband and his new girlfriend.

She too has denied any involvement in the attack.
