Mexican police should quickly and credibly investigate reports that police threatened and attacked journalists covering protests last week and should swiftly bring to justice officers found to have assaulted reporters, the Committee to Protect Journalists said today. State, municipal, and federal police harassed and assaulted journalists covering officers’ forcible dispersal of protests against rising fuel prices in the northern Mexican states of Coahuila and Baja California from January 5 to 7, several journalists told CPJ.
