Customs and Border Protection officials arrested a Mexican national with a history of child sex crimes attempting to cross the U.S. border.

“The incident occurred at approximately 11 a.m., when agents assigned to the El Centro Station encountered a man who illegally entered the United States 22 miles west of the Calexico Port of Entry,” a Customs and Border Protection (CBP) press release notes.

The individual turned out to be a 28-year-old Mexican national previously convicted on May 29th, 2012 for sex with a minor in Santa Maria, California.

He was sentenced to one year in prison and five years’ probation for his sex crime.
