Naco, Arizona - Border Patrol agents from the Brian A. Terry Station arrested a previously convicted sex offender Monday afternoon shortly after he illegally entered the United States near Naco.

Agents apprehended Cirilo Flores-Albino, a 46-year-old Mexican national, less than 20 yards north of the international border and transported him to their station for further processing.

During processing, agents conducted a records check and learned Flores was convicted in 2009 for indecent liberty with a child in Harnett County, North Carolina. He is in federal custody pending prosecution for re-entry as an aggravated felon.

All persons apprehended by the Border Patrol undergo criminal history checks using biometrics to ensure illegal immigrants with criminal histories are positively identified.

U.S. Customs and Border Protection officials welcome assistance from the community. Citizens can report suspicious activity to the Border Patrol and remain anonymous by calling 1-877-872-7435 toll free.
