An attorney for a Utah police department where a white officer drew his gun on a 10-year-old black child says Utah law enforcement will investigate the incident.

Attorney Heather White said Friday the Utah Department of Public Safety has agreed to investigate possible criminal charges against the Woods Cross police officer and evaluate whether he acted with racial bias or unnecessary force.

A lawyer for the child's mother says she is thrilled the state will investigate.

Mother Jerri Hrubes has said the officer pulled his gun on 10-year-old DJ as he played on his grandmother's lawn last week.

Police Chief Chad Soffe said the officer used good judgment when he mistook the child for a potential suspect during a chase.

Protesters are planning a demonstration Friday to demand the officer be fired.
