A 54-year-old Arizona man died after jumping out of a freezer and attacking an employee with a kitchen knife on Sunday at a popular restaurant in Manhattan, the police said.

The man shouted, “Away, Satan!” and grabbed the knife after an employee opened the walk-in freezer at Sarabeth’s on the Upper West Side around 11 a.m., the police said. Workers who heard the commotion came and wrestled the man to the floor and took away the knife, according to the police.

During the brunch-time struggle, the man lost consciousness and went into cardiac arrest, the police said. He was rushed to St. Luke’s-Roosevelt Hospital Center, where he was pronounced dead.

The police did not release the name of the man, who was from Cave Creek, and said he appeared to have mental health issues. Investigators were trying to determine how he got into the freezer and how long he had been there.
