Drug smugglers use road spikes to escape Border Patrol

Drug smugglers were able to escape from Border Patrol vehicles last week after they deployed road spikes.

It happened Friday morning near Rio Grande City.

According to Customs and Border Protection, Border Patrol agents assigned to the area received information regarding a vehicle picking up narcotics. When agents responded to the area they saw the vehicle returning to the Rio Grande River. As agents attempted to intercept, the smugglers deployed "caltrops," disabling two Border Patrol vehicles.

A caltrop is device usually made of metal welded together and designed to puncture tires. If stepped on, it can cause injury to a person or livestock.

Agents later located the suspect vehicle abandoned near the river. Inside, they discovered several more caltrops along with bundles of marijuana. Several people carrying additional bundles were seen heading back across the river into Mexico, according to CBP.

No injuries were reported and no arrests were made.
