Police took one woman into custody tonight after they said she walked into the Monroeville Chuck E. Cheese's with a brick and a knife and started a fight.
Sources said a man was having a birthday party for his son inside the restaurant on Route 22 when his ex-girlfriend walked into the building about 7:30 p.m. and attacked his new girlfriend.
The new girlfriend was taken to UPMC Mercy to be treated for a non-life-threatening wound to the back of her head, officials said.
Another woman who tried to intervene in the fight was bitten in the chest. Her wound was cleaned at the scene.
Police were questioning the woman accused of the attack at the Monroeville Police Department tonight. The woman, whose name has not been released, is expected to be charged with aggravated assault and possibly with other crimes.
