A traffic police director of Santa Catarina municipality was murdered Monday in the northern Mexico state of Nuevo Leon, state police and public security secretariat said.
Enrique Buentello Corpus, 43, was shot dead instantly from at least 15 wounds from AR-15 long-range rifles, as he was driving home in a van around 8:00 a.m. local time Monday.
Police said they have declared a red alert which will remain effective until they find the killers. But no concrete clues have been found yet.
A few hours earlier, armed men fled the scene after firing at least 100 shots at two police officers in San Pedro Garza Garcia, close to Nuevo Leon's capital of Monterrey. The two were slightly injured and have been taken to a nearby hospital.
Monday's attack brought the number of murderees in Nuevo Leon to 69 in the year. 25 of them were police officers and 10 officers were from Santa Catarina. Five of the Santa Catarina killings took place in just four days.
Separately, also in Monterrey, 150 police officers staged a stay-down strike to protest their low salaries and the scant resources they have to fight crime.
Local media reported that Mexico has seen 1,089 mostly drug-related murders in the year to date.
