Police say a group of adults attacked employees at a Chuck E. Cheese's in a Cleveland suburb when a manager didn't respond quickly enough to a complaint about a malfunctioning photo booth.

A Parma police spokesman says six employees of the child friendly restaurant and arcade were attacked and injured Sunday night.

Lt. Kevin Riley said Tuesday that police have a number of leads and tips and hope to make arrests in the next few days. He says at least five men attacked the employees of the Irving, Texas-based chain while a dozen partygoers urged them on.

The attack apparently began after a woman told the manager a photo booth wasn't working and the manager told her she'd have to wait.
