A senior police officer was gunned down in front of a bus station in the Mexican resort city of Acapulco, local officials said.
The police commander was killed Saturday in his personal car while passing the station that is a hub for bus lines used by tourists to get from the capital to Acapulco, a local prosecutor told AFP. The officer's son, who was with him, was unhurt.
In a statement, the local government condemned the killing and asked state attorneys to mount a rapid investigation.
Acapulco is in the impoverished Guerrero state that has struggled with drug-related gang violence. Schools were put under military protection in February following a teacher's strike in response to the lack of security.
Last month, Mexican authorities arrested the suspected leaders of the Independent Cartel of Acapulco, believed to be responsible for much of the resort city's violence, kidnapping and extortion.
