Two arrested in Reynosa for allegedly building cartel radio system

Two electrical engineers have been arrested in Mexico for allegedly erecting and maintaining a radio network for a drug cartel on the country's northern border.

In a statement Wednesday, the Tamaulipas state government says the two men were arrested in Reynosa, a city across from McAllen, Texas.

Authorities seized 20 radio frequency kits, seven repeaters, 12 antennas among other equipment. Police say the two men were arrested as they unloaded items from a pickup truck, including marijuana and an improvised grenade launcher.

The statement says the men were responsible for installing antennas for the cartel's radio network along the border. So far this year, authorities in Tamaulipas have taken down 65 antennas that the cartel used for radio communication.

Mexico's northeast border region is the territory of the Gulf cartel.
