Arrests and detentions at the U.S.–Mexico border hit record levels in April, although fewer unaccompanied minors entered the United States illegally, according to U.S. Customs and Border Protection (CBP) data published on May 11.
Immigration arrests and detentions at the southern border last month rose by 3 percent from March, to 178,622—the highest one-month total in 20 years, CBP data show. In contrast, the number of teens and children arriving unaccompanied last month declined by about 9 percent from March, to 13,962.
