Border agents in Arizona stopped four accused or convicted sexual predators from illegally entering the U.S. over the weekend.

U.S. Customs and Border Protection said Monday that on Sunday, Casa Grande agents arrested a 34-year-old Mexican man with a rape conviction in Oregon.

On Saturday, Ajo station agents arrested a 34-year-old Mexican man who was convicted in Fresno, Calif. of sexual assault on a child under 14. They also arrested a 24-year-old Mexican man who had a mass storage device containing child pornography.

And on Friday, agents found a 24-year-old Mexican man near Naco who had an active warrant for aggravated criminal sexual abuse in Woodstock, Ill.

The man with the warrant was turned over to Tucson police for extradition, while the two convicted men are being prosecuted for re-entry of an aggravated felon.

The man who had the child pornography was turned over to U.S. Immigration and Customs Enforcement for further investigation.
