Bellevue Police Wednesday helped bust a major marijuana-growing operation near the Tiger Mountain Summit, netting at least one dump-truck load of pot plants.

KING-TV reported that a hunter tracking a bear spotted a plant two weeks ago, and today a SWAT team and other law enforcement harvested 25,000 plants.

Police said two to four Mexican nationals may be behind the growing operation.

“We located signs posted on trees and their encampment with the names of Mexican states, presumably their home states,” Police spokeswoman Carla Iafrate told KING-TV.
