Border Patrol agents in just one sector of the besieged southern border arrested three convicted sex offenders in the space of four days, Customs and Border Protection (CBP) announced this week.

The apprehensions all took place in the Del Rio Sector of the border and began on Jan 2., when agents apprehended a 45-year-old Mexican national with a prior conviction for indecency with a child. 

He had been sentenced and later deported in 2005 for the crime. Agents encountered him coming across among a group of six migrants trying to sneak past agents inside a rail yard.

On Thursday, agents in Eagle Pass – one of the focal points of illegal crossings along the border – agents arrested a 27-year-old Mexican who had a conviction of indecency with a child from 2016 and a second for failing to register as a sex offender the following year. He had most recently been deported in 2019.

The same day, agents nabbed six illegal immigrants trying to evade Border Patrol in a local ranch. One of those men in that group was a 43-year-old Mexican with a 2011 conviction for sexual assault in Austin, Texas.

In a news release, CBP said that all the offenders face a potential charge of re-entry after deportation.
