A teenage girl was allegedly raped while at work by two boys in connection with a kiosk robbery on Sunday night.
The two suspects were put into police custody on Thursday afternoon after police arrested the pair on Wednesday night, TV2 reported.
A 16-year-old boy is charged with rape while a 17-year-old currently only faces robbery charges, according to VG.
The 16-year-old's lawyer said that his client did not acknowledge guilt.
The two young robbers allegedly threatened the teenage girl with a knife and assaulted her in a kiosk in western Oslo on Sunday. Police technicians secured several clues on the premises and also obtained surveillance videos from the area.
“We have worked very intensely on this case. It is both a brutal robbery and a young girl who was alone on the job was subjected to a serious sexual assault,” Grete Lien Metlid from Oslo Police told TV2.
According to VG, the two are also charged in another Oslo rape that allegedly took place at around the same time.
Both teens have previous convictions, police said. Police will hold them in custody for the next two weeks while their investigation continues.
Police had considered publicly releasing surveillance images of the two perpetrators but cancelled their plans when the pair were arrested on Wednesday.
