Border agents at the U.S.-Mexico border intercepted a "seedy situation" when they encountered over $5 million in methamphetamine disguised in inflatable watermelons in the continued saga of Mexican cartels attempting to smuggle illicit drugs through the border.

U.S. Customs and Border Patrol (CBP) agents grew suspicious of a 29-year-old man who was driving a commercial tractor-trailer filled with watermelons. 

Authorities said the tractor-trailer was seeking to gain entry into the U.S. at the Otay Mesa Commercial Facility near San Diego.

A secondary point of inspection discovered that, among the shipment of actual watermelons, around 1,220 fake watermelons were found to contain 4,587 pounds of methamphetamine.

Further inspection revealed the illicit drug was carefully packaged in an inflatable-like watermelon disguise.

The contents of the packages were tested and identified as methamphetamine with a total weight of 4,587 pounds and a street value of more than $5 million.

"I am incredibly proud of our team for their exceptional work over the past few weeks in uncovering sophisticated and diverse smuggling methods," Hernandez said. "As drug cartels continue to evolve their smuggling techniques, we will continue finding new and better ways to prevent these dangerous drugs and other contraband from entering the country."

Robert J. Murphy, special agent in charge of the DEA Atlanta Division, said the seizure shows the "confidence" of the Mexican cartels.

"This is a significant and unbelievable amount of drugs to be shipped at one time and to a destination this far from the border," Murphy said. "It also shows the confidence of the cartel behind this."
