A Connecticut man was arrested for stabbing a Walmart clerk over the price of milk, police said.

The assault happened shortly after noon Sunday at a Walmart in Waterbury, the Republican-American reported.

Forty-year-old Hichman Asfir, of Stamford, stabbed the cashier in the head with a folding knife after she scanned a gallon of milk and told him the price, police said.

Asfir was arrested on charges including first-degree assault, police said. He was awaiting arraignment Monday. It wasn’t clear if he had an attorney who could speak for him.

The 19-year-old victim was hospitalized for treatment of a puncture wound behind her left ear. She was in stable condition Sunday night.
