Two women were arrested and two people were injured after a brawl involving as many as 20 people at a Chuck E. Cheese restaurant in Deptford spilled outside on Sunday evening, authorities said.

A woman who suffered a minor stab wound to the hip refused treatment, Deptford police said. A worker who tried to break up the altercation also was hurt trying to separate some of the combatants.

The fight broke out at the eatery on Almonesson Road around 6 p.m, Sunday.

Cops from Gloucester Township, Woodbury, Woodbury Heights and West Deptford had to help break up the melee.

Police didn't detail the charges against the two women taken into custody.

Anyone who witnessed the fight is asked to call Det. Tim Parks at 856-845-6300, ext. 1225.
