Shortly after 9pm on Sunday, police say they arrested a man in his 30s and charged him with the murder in Greenland.
The man was arrested at an address in Oslo, and has been known to police before.
They will try to question him during the evening.
The 30-year-old’s lawyer, Tor Even Gjendem, told NTB on Sunday evening it was too early to comment on the case.
– To reject
On Sunday morning, a 20-year-old man was arrested and charged with complicity in the murder.
He was questioned by the police on Sunday evening.
Defense attorney Inam Ghous Ali says the man is having a hard time and denies any involvement in the murder.
In a press conference at 3pm, police say the killing in Greenland bears the hallmarks of a gang settlement.
The person killed is a 20-year-old Norwegian, residing in Oslo. He has been well known to the police since before and has previously been convicted of several matters. He belongs to a criminal ring. The police therefore believe that he was not a random victim.
According to NRK, the murdered man testified in several court cases.
– It’s something we need to investigate to see if it could be.
– What are the other theories then?
– There are several hypotheses. We’re working extensively on what the background for this might be, replies Hansen.
Several people involved
Two people have so far been taken by the police after the murder. One of them, a man in his 20s, is accused of complicity in murder and will be questioned on Sunday. Police are not ruling out other arrests in the case.
– We have a decent description of the person in question and we have relevant candidates we are working with. We don’t think these are random shootings, so with the information we have, there’s no reason to believe there’s a danger to the public in the area, says operations manager Line Skott of the Oslo police.
They won’t say anything about the weapons seized in the case.
Killed in Greenland
It was at 04:18 am that police were informed by witnesses at a subway station in Greenland that one person had been killed.
– The person was first treated by paramedics but was pronounced dead on the spot shortly after, police said on Twitter.
– We arrived at the scene early and found a man who had been shot and with injuries not compatible with life, so he was pronounced dead early. In retrospect, we worked with a lot of crews in the area around Grønland/Brugata looking for the people described, manager Rune Hundere tells NTB.
The relatives of the deceased have been notified.
Police say they take the Greenland murder case on Sunday night very seriously. Also earlier this week, one person was seriously injured when shot at Furuset in Oslo.
– Both incidents bear the mark of an agreement between criminals. The Oslo police have stepped up their efforts against criminal circles, says police inspector Jan Eirik Thomassen in the Oslo police district.
He says that in the future they will have more visible police on the streets of Oslo. At the same time, they will strengthen the work to investigate cases related to criminal rings and bring them to court faster. Preventive work must also be strengthened.
– We are now working on getting an overview of what the background may be and if there are any links between the various events that have occurred. There have been many different incidents this fall alone, says Ingebjørg Hansen from the Oslo police district.
