Laredo South Border Patrol agents intercepted 11 illegal aliens who entered the U.S. through a drainpipe near the Rio Grande in Laredo, Texas.

After hearing voices echoing from the drainpipe, agents quickly moved in and made the arrest.

Human smugglers have been exploiting Laredo’s underground drain system for years — a tactic straight out of a Teenage Mutant Ninja Turtles movie.

These drainpipes allow smugglers to move illegal aliens into the city, popping up anywhere in the downtown area and neighborhoods near the Rio Grande.

This tactic is extremely dangerous — where conditions inside the tunnels can quickly become life-threatening.Outstanding work by the agents!
