Teenager charged with sushi restaurant grenade attack linked to alleged mastermind Ali Namdar

A 16-year-old was indicted for throwing a hand grenade into a sushi restaurant in central Strømmen, an incident that caused no injuries. He has confessed to the grenade throw but rejects liability under the organized-crime statute. During the trial, authorities presented Signal messages sent from an account named “Joker,” which prosecutors believe was operated by Ali Namdar, though the lack of a unique ID prevents definitive proof.

Namdar is already under investigation for several violent offenses in Norway, including earlier grenade attacks and shootings, and faces additional charges for alleged murder conspiracies and human trafficking. Police argue that the teenager was used as a pawn in a broader criminal network, but Namdar’s stance on the allegations has not been disclosed.
