He was a Norwegian blond guy wearing a beard and a wig trying to frame muslims.
I haven’t seen a picture, but his name doesn’t sound like he is of the tribe.
“The man is captured on video pulling the 12-inch hatchet from a black backpack, police say.
While Bratton said authorities were working to identify the assailant, police sources told NBC News that the attacker had been tentatively identified as Zale Thompson, a 32-year-old man with a Facebook page containing images of what appears to be a Muslim warrior and prayers. However, authorities have found no links to extremist literature or jihadi groups at this time.”
