WESTBURY, N.Y. (AP) — Police say a man carrying a hunting knife crept up behind an 8-year-old boy playing a video game in a New York restaurant and plunged a 4-inch blade into his back five times.

The boy suffered a punctured lung in the assault just before 8:30 p.m. Friday in a Westbury shopping mall on Long Island. He is expected to recover.

The attack happened at Dave and Buster's, a family friendly chain restaurant that includes an arcade.

Police say the boy's father and a witness grabbed the suspect as he walked toward a restroom and held him until officers arrived.

The 23-year-old suspect is set for arraignment Saturday on charges including attempted murder.

Nassau County Police detective Lt. Kevin Smith says the suspect appeared to have chosen his victim at random.
