MARIETTA, Okla. (KTEN) — Marietta police conducted a traffic stop on Interstate 35 around 4 a.m. Thursday. It led to the seizure of about 166 pounds of illegal marijuana.

Police said an officer observed a vehicle driven by the suspect, Sun Di Yi, 36, traveling under the speed limit on the highway committing minor traffic violations.

After being pulled over, multiple black trash bags were observed in the back seat of the vehicle. A K9 unit from the Chickasaw Lighthorse Police Department was summoned, and the black market marijuana was discovered.

It's the biggest drug bust for Marietta police in the last 10 years.

"The marijuana is worth about $166,000 in Oklahoma; that goes up with mark-up being transported to Texas, with an estimated value of about $2,000 a pound," said Marietta police Chief Brett Harris.

After court proceedings police will transfer the marijuana to the Oklahoma State Bureau of Investigation for disposal.

Yi is scheduled for an initial court appearance next Thursday on a charge of trafficking in illegal drugs.
