Bodies of 10 people allegedly murdered by organized crimes were found on Wednesday morning in two mass graves in eastern Mexico's Veracruz state, the Mexican navy said.

The navy said the graves were found in two ranches in Acayucan city, nearly 540 km southeast of Mexico City, following the arrest of a man on Tuesday.

In a joint statement released by the navy and the local government of Veracruz, the murder of the 10 persons was attributed to the drug gang "Los Zetas."

Acayucan, located in south Veracruz, is a livestock farming area, which is considered by local and federal authorities as a "hot spot" of great danger, because of growing insecurity in the region.

On Tuesday morning marines arrested the occupant of a vehicle that tried to evade a checkpoint set up near Acayucan.

The man, identified as Juan Francisco Alvarado Martagon, alias "El Pollo H," confessed himself as chief of a criminal group in the service of "Los Zetas."

The suspect later pointed out the exact locations of the two mass graves.

During Tuesday night and early Wednesday, staffers of the Attorney General of the state carried out excavations and uncovered the 10 bodies, which were in state of decomposition.

Last October, the Mexican government launched the operation "Veracruz Insurance" by deploying federal forces and strengthening intelligence work to ensure security in the area shaken by a wave of violence.

The move came after the findings of 32 bodies in three homes, and other 35 bodies dumped on a busy avenue in the tourist area of Veracruz on the Gulf of Mexico.

More than 47,000 people have been killed in drug-related violence in Mexico since President Felipe Calderon launched the "war against organized crimes" in 2006.
