MEXICO CITY—Mexican authorities have arrested a municipal police chief for his suspected links to the killing of three women and six children of U.S.–Mexican origin in northern Mexico last month, local media and an official said on Friday.

Suspected drug cartel hitmen shot dead the nine women and children in Sonora state on Nov. 4, sparking outrage in Mexico and the United States.
