A stabbing victim walked into a New York City McDonald's restaurant with a knife stuck in his back, before collapsing and receiving medical care.

The man was speaking on his mobile phone, apparently to family members, as he entered the restaurant, eyewitnesses told media. The incident was filmed by other restaurant goers.

“He was on the phone, I’m pretty sure he was on the phone talking to somebody in his family or a loved one or something, he was talking to them and telling them it might be the last time he’s speaking to them,” witness Tromaine Yancey told news channel CBS 2 local affiliate

Customers in the Queens restaurant reportedly rushed to help the victim and prevent him from falling on the kitchen knife. The victim, who was apparently stabbed in retribution for an earlier incident, is in hospital in a serious condition.
