Beatdown with a side of bread.

A Panera Bread pan-wielding worker repeatedly bashed a crazed customer in the head when he started to assault employees and customers in a violent outburst inside the Colorado fast-casual restaurant.

The suspect, identified by the Glendale Police Department as Isaac Ross, started wreaking havoc inside a Panera Bread in Glendale — five miles outside of Denver — on Tuesday, according to KDVR.

A video taken by frightened customer Natalie Wiersma showed the suspect screaming like a maniac, chucking items off the counter at the restaurant’s staff, and demanding the workers return a phone.

“The suspect was yelling it at the workers, and they were all super confused-looking and said, ‘We don’t have your phone,” Wiersma told the outlet.

Customers tried pleading with Ross to stop and leave, but it seemingly infuriated him further.

Ross is heard shouting a racial slur at one diner before continuing to unleash his temper tantrum in front of other customers.

“No one has your phone!” a customer screams at Ross as he continues his threatening antics.

The suspect is then seen moving around to the front of the counter, where he hurls more items at the staff.

Seconds later, a customer rushes up behind Ross and tries pushing him away, but Ross quickly turns around and knocks the Good Samaritan to the floor.

Ross leaps forward at the defenseless man, swinging his arms on the attack.

He lands a slap on the man before another customer comes and wrestles him to the ground.

“The next guy then actually kind of saved that guy from getting attacked further and tried his best to hold them down,” Wiersma told the outlet.

A Panera Bread employee appears with a long bread pan and strikes Ross across the head five times as another customer tries to restrain him.

“My personal hero,” Wiersma shared. “That I think was very effective.”

Someone shouts, “Call the police,” as the suspect and fearless customer continue to grapple on the ground before the video ends.

The Glendale Police Department told the outlet that Ross fled from the scene soon after the altercation.

However, they shared that he later returned to the same Panera and had another violent outburst.

Ross allegedly assaulted an at-risk male victim, law enforcement said about the second disturbance.

That victim needed to be treated for minor injuries.

Police are asking the public to come forward with any information leading to Ross’s whereabouts.

The Post has contacted the Glendale Police Department and Panera for comment.
