A group of armed gunmen stormed a bear distribution warehouse in the northern Mexican city of Monterrey Friday, killing 10 people dead in broad daylight, officials said.
The dead were employees of beer brand Corona's distribution warehouse in Garcia municipality in the Monterrey metropolitan area in Northern Mexican province of Nuevo Leon, BBC News reported.
Seven people were dead were found naked on the site, and three wounded were taken to University Hospital but died there, according to Vanguardia.
"The armed group came to the warehouse of a beer distribution agency and opened fire on workers who were present," Nuevo Leon Security Council spokesman Pablo Gamez told El Universal.
Armed gunmen arrived at the warehouse around 2 p.m. local time (7 p.m. GMT) on Friday and demanded money from the workers before shooting them down, Milenio reported. They also got away with 10,000 pesos ($650) in cash.
Neuvo Leon province attorney Javier Flores suspected that the attack was a gang war between two rival groups of people linked with drug trafficking, CNN Mexico reported.
"So far the preliminary line of investigation we have is that this is an attack between members of organized crime," Flores said.
Police have found about seven kilograms of drugs, a scale, a rifle calibre 223 and a box of .45 bullets, according to Proceso.
Garcia is the hometown of the next governor of Nuevo Leon province Rodriguez Jaime Calderon, who said he is sad and angry about the attack and demanded that authorities focus on finding the culprits rather than giving an explanation.
"Police and authorities should not relax. They should seek to find the culprits, sparing no one. They should not allow the wave of violence back," Calderon said.
The incident is the biggest organized crime attack in Monterray after a year of peace. Zetas cartel gunmen shot down 52 people in broad daylight in a casino in 2011.
