U.S. Border Patrol agents from the Rio Grande Valley Sector say they seized nearly $5.2 million worth of marijuana throughout the past week.
Authorities said agents made the largest seizure near Rio Grande City on Wednesday when personnel aboard a helicopter spotted a van driving away from the Rio Grande.
Agents on the ground intercepted the vehicle and confiscated nearly 1,200 pounds of marijuana, according to U.S. Customs and Border Protection.
Authorities said another large bust was made near La Casita on Thursday when agents working near the river saw several people loading bundles of marijuana into a Ford Expedition.
As the agents approached, officials said the smugglers fled into the brush, abandoning nearly 1,000 pounds of marijuana.
Several additional seizures brought the total amount of marijuana seized from Sunday through Thursday to nearly 6,500 pounds, according to U.S. Customs and Border Protection.
