Authorities have arrested a 48-year-old Waite Park man and confiscated more than $550,000 worth of high-grade marijuana. Stearns County Sheriff John Sanner says the Central Minnesota Drug and Gang Task Force had been investigating for two months on tips from the Montana Highway Patrol and other sources.

On Tuesday, investigators found 146 pounds of marijuana at a storage facility in Sartell. Sanner says it has a street value of between $3,800 and $4,000 a pound. It was individually packaged in one-pound vacuum sealed bags. Authorities believe it came from Canada. Then officers searched a home in Waite Park where they found $22,000 in cash, a rifle and a handgun.

Tu Van Tran, the suspect, was arrested at his job Tuesday, and is being held pending drug charges.
