New York City police say a man has been treated for a non-life-threatening injury after walking into a McDonald's restaurant with a kitchen knife stuck in his back.
Chief of Detectives Robert Boyce told reporters Wednesday that investigators have recovered video of the argument between four men that preceded the Tuesday stabbing.
Boyce says the victim has been treated at a hospital and has spoken to detectives but has not been cooperative.
Police say officers responded to the fast-food restaurant in Jamaica, Queens, at about 10 a.m. Tuesday after receiving 911 calls from inside the restaurant.
Witnesses tell local media the man was chatting on his cellphone and appeared composed despite the knife in his back. They say his T-shirt was stained with blood.
There have been no arrests.
