A police K-9 in California sniffed out an estimated $300,000 in suspected drug money during a traffic stop, authorities said Monday.

Beny, a K-9 officer with the California Highway Patrol (CHP), was called on to sniff a Chevy Tahoe on Dec. 21 in Merced, the department said in a statement. A CHP officer had pulled over the vehicle for tailgating and noticed several things that led to suspicions of criminal activity.

Beny sniffed the vehicle’s exterior and gave a positive alert to the odor of narcotics, the CHP said.

Officers then searched the vehicle and found a suitcase and backpack filled with a large amount of cash, the statement said. Investigators believe the money came from the sale of drugs.

While an official count is pending, officers estimated the cash amounted to around $300,000.

Officers seized the money and the driver was arrested. A charge of possessing over $100,000 of money related to drug sales was pending, the department said.

The incident was one of several high-profile busts Beny and the CHP made this month.

On Dec. 11, Beny busted a driver who was found with two suitcases and a black briefcase filled with $1,017,750 in cash, the department said. Investigators believed the money also came from drug sales.
