A 4-year-old boy is critically wounded after being hit with a stray bullet from a rolling gunbattle while helping celebrate his mother’s birthday.

Police say a friend of the family was holding the child Saturday evening when a bullet struck the man in the hand and then hit the boy in the stomach.

The Kansas City Star reports dozens of people were celebrating around 8 p.m. when two cars made a U-turn nearby and the shooting started.

Police say the shooting began after an altercation they believe started outside a convenience store. Police did not have clear descriptions of the vehicles involved and have not released descriptions of the shooters.

The child was listed in critical condition Saturday night, and police on Sunday said his condition hadn’t changed.
