STREETSBORO - Officers from several Portage County police agencies seized more than 500 marijuana plants estimated to be worth about $500,000.

Portage County Sheriff Duane Kaley said an indoor hydroponic growing operation at 1175 Sparrow Run is one of the largest of its type seized by officials in Portage County.

The home's owner, Tien Q. Lam, 54, was arrested Tuesday and is expected to be arraigned today in Portage County Municipal Court in Ravenna. Kaley said Lam is facing a second-degree felony charge of cultivation of marijuana.
