A man hit a 77-year-old woman on the head with a metal pipe, before stealing one of her pizzas.

In a video, released by the Tucson police Department, a woman carrying two pizzas attempted to leave Peter Piper Pizza, in Arizona.

A man, who was waiting outside and holding a metal pipe, opened the door and confronted her as she attempted to leave.

He hit her on the head with the pipe and fled the scene with one of the pizzas, while the woman ran back inside the pizzeria.

According to the police department, the incident occurred at around 3:45pm on 21 April.

On Tuesday, the Tucson Police Department released the video and a statement, where they asked for help from members of the public.

“The suspect was described as a dark-complected Hispanic male, in short stature. 5’6” or shorter. He was also reported to have a ‘wrinkly face,’” the statement read.

“We know the video isn’t very clear, but if you frequent this area and have seen someone matching this description, please call so we can get this guy off the streets.”
