The FBI arrested yet another U.S. Border Patrol agent this week after watching him go to the border fence near Wellton, Ariz. and pick up bales of marijuana.

After his arrest, the investigators asked agent Aaron Anaya if he'd speak to them.

"I'm f***ed," he responded, according to an affidavit by FBI special agent Jesse Marotta. "You guys got me on video."

Then Anaya clammed up, the affidavit says.

The arrest of Anaya is the latest of many U.S. agents on the border, as my former colleague Brady McCombs showed in this story last year. 

Federal agents apparently had been watching Anaya. They had both fixed-wing and rotor craft (planes or drones and helicopters) in the air Sunday evening when they saw Anaya's Border Patrol vehicle pull up to the fence, the affidavit says. 

A vehicle pulled up from the Mexican side, and three men passed bags over the fence to Anaya, who loaded them into the Border Patrol vehicle and drove away, Marotta said in the affidavit. The agents arrested Anaya at about 10:40 and found in his official vehicle three duffel bags containing 147 pounds of marijuana.

Anaya faces charges of possession of marijuana with intent to distribute, and possessing a firearm in a drug-trafficking crime.
