Sheriff’s narcotics investigators arrested two men and discovered about 2,000 marijuana plants with an estimated street value of $6 million at three grow houses in Diamond Bar and Hacienda Heights on Wednesday.

The marijuana plants were in various stages of growth.

Sgt. Jim McGee of the sheriff’s Narcotics Bureau said a tip led them to a house in 23200 block of Forest Canyon Drive in Diamond Bar. Deputies arrested two men seen coming out of the house.

McGee said further investigation led to two other locations – a house in the 20900 block of Running Branch Road in Diamond Bar and a residence in the 17000 block of Glenfold Drive in Hacienda Heights.
