The teenager was remanded into custody by Stockholm district court on suspicion of murder after the killing of the man on the open street in the Kungsholmen area of the city.
He is being held on the highest grade of suspicion, probable cause.
“He is down and is reflecting on his situation,” the teenager’s lawyer Ola Salomonsson said.
Salomonsson said that the boy opposed the basis on the remand order but accepted the grade of suspicion levelled against him.
“He has conceded probable cause for the statement, I don’t want to say it in any other way.”
This is not the same as either a denial nor a confession, he underlined.
The 22-year-old man was shot and killed while sitting in a car parked outside of a restaurant on Scheelegatan in the Kungsholmen area of central Stockholm, shortly before 6.20pm.
Police received an alarm almost immediately and the teenage suspect was arrested in the vicinity of the crime scene, which is close to the main police station.
The suspected murder weapon was recovered nearby.
