ASHLAND, Wis. (WSAU) – For the second time in two years, the federal agents have busted a large marijuana grow in the Chequamegon-Nicolet National Forest.

Spokesperson Suzanne Flory says the grow site is several acres but didn't know initially how many plants had been pulled. Flory says the public should be aware of anything suspicious, but not to be overly concerned. “If you see anything suspicious, just back away and call police.” Most of the grow operations are located in out-of-the-way locations in the forest.

175 federal, state and local law enforcement agents were involved in the operation. The U.S. attorney says one person is under arrest so far, and authorities are on the hunt for four others. A tip from a local hunter lead authorities to the site.
