The Norwegian Attorney General Tonje Tønder tells NRK that everything indicates that it was the gang leader Isamil Abdo who ordered the deed.
The man who was hit by the shots was severely injured and was hospitalized for several months. It wasn't until half a year after the incident that he could be heard by the police.
A fourth man, a Syrian citizen, is also being prosecuted for attempted murder. All four defendants deny the crime.
NRK writes that the attempted murder is one of more than 40 cases in Norway that can be linked to Swedish criminal networks.
