A child's birthday party at a Chuck E. Cheese restaurant in Massachusetts was cut short when a fight broke out between two mothers.

The mother of the 9-year-old birthday boy apparently became enraged because the other woman's son was "hogging" an arcade game, Natick, Mass., police said.

Catherine Aliaga, 38, and Tarsha Williams, 33, both of Boston, will be summoned into court to answer charges of simple assault and battery stemming from the scuffle, Sgt. Paul Thompson said.

Thompson told the MetroWest Daily News that police received a number of 911 calls about the fight Saturday night.

He said what started as a birthday celebration turned into a "birthday melee."
