More than 100 officers, the entire police force of the town of Linares, Mexico --75 miles (120 kilometers) southeast of the northern industrial city of Monterrey -- were herded into buses and driven to a nearby town, Linares Mayor Francisco Medina Quintanilla told Milenio Television on Sunday.

They are being held for investigation of possible corruption and ties to organized crime. Mexican soldiers and Nuevo Leon state police are patrolling instead.

The detention of more than 100 officers comes after a rise in kidnapping and extortion in the area. A series of investigations in other towns already has put hundreds of officers in custody.

The military action comes as Monterrey and the surrounding region have been the scene of an ongoing war between the Zetas and Golfo drug cartels.

It also follows a push to crackdown on corruption within local police forces. The Mexican Armed Forces or Federal police officers have been sent to several hotspots throughout Mexico to supplement often corrupt, intimidated or weakened local police.
