Mexico City  - Mexican police have arrested Hector Huerta Rios, believed to be among the top 37 drug traffickers on the country's most-wanted list, the public prosecutor's office said Wednesday.

Huerta Rios, who was arrested on Tuesday, was considered the most influential person in the Beltra-Leyva drug family in the northern Mexican city of Monterrey.

His arrest was announced on the day US Secretary of State Hillary Rodham Clinton arrived in Mexico on her first visit, with the fight against drugs at the top of her agenda.

Huerta Rios' arrest came after the Mexican public prosecutor's office offered a reward of 1 million dollars for information leading to the arrest of 24 drug lords and 13 lieutenants belonging to six cartels.

The alleged drug trafficker was arrested by the Army in San Pedro Garza Garcia, Monterrey. Three rifles, one submachine gun, four guns, four grenades and 18 luxury vehicles were seized in the raid. (dpa)
