PARMA, Ohio -- At least five patrons were involved in an attack on employees at Chuck E. Cheese's in Parma, police said.

The incident happened about 7:15 p.m. Sunday during a birthday party at the West Ridgewood Drive restaurant and entertainment center.

The patrons involved in the fight fled before police arrived, and no one has been arrested at this time, Parma Lt. Kevin Riley said.

Two employees were seriously injured and taken to University Hospitals Parma Medical Center to be treated following the incident. They have since been released, Riley said. Another three employees also received hospital treatment.

A man confronted a Chuck E. Cheese's manager near the kitchen because a game was not working. He began beating the manager, and at least four other patrons joined in, Riley said.

"It wasn't a fight," Riley said. "It was an attack."

At least five employees came to the manager's aid.

Parma investigators are working to obtain security video from Chuck E. Cheese's corporate office while they follow other leads, Riley said.

Audio of 911 calls from employees to police can be heard here.
