The man, who is in his late teens, has also been detained. The suspicions are of a lower degree and his lawyer tells P4 Kristianstad that he denies the crime.
Evelina Olsson, the police's press spokesperson, says it's too early to answer whether the shooting is gang-related.
We're not going into details due to the investigation, she says.
On Thursday, the police will continue their work on gathering information. A technical investigation has been conducted and material from cameras in the area has been collected.
We have witnesses in the case, but we're still interested in tips, says Olsson.
The alarm about the shooting at a gas station came in at around 10 pm on Wednesday. The police later announced that a man in his 20s had died. The man's relatives have been informed.
