RACINE COUNTY, WI (WTAQ) - Almost $7.5 million worth of marijuana was seized Monday in a raid at a Racine County farm.

An anonymous tip led Greenfield police officers to a high-tech growing operation in a pole barn in the town of Raymond.

Media reports said numerous law enforcement agencies conducted a search of the property. They found 1,800 pounds of marijuana, $100,000, and a number of firearms.

No one was immediately arrested, but officials say charges are expected.
