Del Rio Sector Border Patrol agents arrested a group of 51 migrants who attempted to sneak into the U.S. illegally.

Carrizo Springs Station Border Patrol agents patrolling along the Rio Grande observed “discrepancies on a trail” leading from the river. The agents started tracking the migrants and called for assistance from U.S. Customs and Border Protection (CBP) Air and Marine Operations (AMO). Officials with AMO dispatched a helicopter crew to assist in the search for the group, according to Del Rio Sector officials.

The aircrew helped locate the migrants and guided ground-based agents to their location. The agents placed the group of 51 migrants under arrest and began an immigration interview and initial assessment.

Following the initial interview, the agents identified all 51 migrants as Mexican nationals. They determined seven of those to be juveniles over the age of 15.

The agents turned all 51 migrants over to the Laredo West Border Patrol Station due to the location of the apprehension. The agents transported the migrants to the station where they will be processed for immigration violations.

Laredo Sector Border Patrol Agent Hector Garza, in his capacity as vice president of the National Border Patrol Council, told Breitbart Texas over the past weekend that migrants are more frequently attempting to evade arrest and are finding more traditional means of being smuggled into the U.S.

“We have also seen an increase in the strategy of packing human cargo into big-rig trailers,” Garza continued. “This appears to be happening as more OTMs (Other than Mexican) migrants are returned to Mexico under the MPP policy. As the migrants figure out they can’t just arrive and stay, they begin to seek more traditional human smuggling tactics to get into the country.”
