BROOKLYN PARK, Minn. (AP) _ Brooklyn Park police said Friday they've made an arrest in the sexual assault of a 6-year-old boy in a portable toilet in a local park.

Officials say the boy's family was having a gathering in Willowstone Park Wednesday when the child disappeared.

A family member then saw the boy coming out of a port-a-potty followed by an unknown man.

The child's family later learned that the boy had been sexually assaulted inside the port-a-potty.

Police say they received a tip about a possible suspect and arrested a man who lives near the park on Friday. Authorities say the suspect was uncooperative and resisted arrest.
