Border Patrol agents have arrested two convicted sex offenders and two MS-13 gang members who were all previously deported.

The arrests occurred in four separate incidents this week near the border in Arizona and Texas, according to U.S. Customs and Border Protection.

On Wednesday, agents arrested a 46-year-old Mexican national, after he illegally entered the U.S. near Lukeville.

During processing, agents discovered he was convicted in 2002 of unlawful sexual conduct with a minor in Mesa, Arizona.

Then on Thursday evening, Nogales Station agents arrested a 24-year-old national of El Salvador.

During processing, agents conducting records checks learned that he is a member of MS-13, a violent trans-national criminal organization operating in many parts of the U.S.

Both subjects are considered felons previously removed from the country and now face federal criminal immigration charges, CBP said.

The agency noted that all persons apprehended by the Border Patrol undergo criminal history checks using biometrics to ensure illegal aliens with criminal histories are positively identified.

Earlier this week in Texas, Border Patrol agents also arrested a sex offender and MS-13 gang member who tried to cross the border illegally.

In San Diego, Border Patrol agents are seen from Tijuana on Saturday detaining a Honduran asylum seeker after he crossed the U.S. border illegally

On Wednesday in Eagle Pass, Texas, agents arrested a 26-year-old Honduran national after he illegally entered the United States.

Record checks revealed he has a criminal history, including a conviction in 2012 for sexually fondling a child in New Brunswick, New Jersey, CBP said.

The man was sentenced to serve 255 days in prison and is registered as a sex-offender. He was removed from the U.S. in 2013.

On Tuesday, agents assigned to the Eagle Pass North Station arrested a Honduran national near Eagle Pass shortly after he made an illegal entry by crossing the Rio Grande River.

Records checks revealed that he had been previously deported and that he is a confirmed member of the notorious MS-13 gang.

His prior order of removal will be reinstated, and he faces prosecution for reentry after deportation, which carries a maximum sentence of 20 years in prison.

On Friday, Supreme Court struck down a proposed ban on allowing asylum claims from people who illegally cross the border between ports of entry.

Chief Justice John Roberts joined his four more liberal colleagues in ruling against the administration in the case.

New Justice Brett Kavanaugh and three other conservative justices sided with the Trump administration in favor of allowing the ban.

There were no opinions explaining either side's votes.
