Border Patrol stopped four illegal migrants who are sex offenders, some with convictions of crimes against children, at the southern border in just one day this week.

Border Patrol Chief Jason Owens said in a tweet that agents arrested the four sex offenders on Wednesday.

The four arrested had charges including “sexual abuse of a child,” “rape by force/fear,” “indecency with a child and aggravated sexual assault,” and “indecency with a child, exposes,” Owens said.
