The entire police force of a small northern Mexican town quit after gunmen attacked their recently inaugurated headquarters, says an AP report.
 
Los Ramones Mayor Santos Salinas said nobody was injured in Monday night's attack, during which gunmen fired more than 1,000 bullets at the building's facade, according to the report. Six grenades, of which three detonated, were also flung at the building, the report said.
 
Los Ramones is in Nuevo Leon, a state torn by fighting between the Gulf and Zetas drug gangs. Police stations in small northeastern Mexican towns are frequently attacked, and several mayors have been assassinated, the report says.
 
It was the second attack in less than a week against police installations in the state of Nuevo Leon. On Oct. 19, two grenades were thrown at a police shelter in the town of Sabinas Hidalgo.
