ROSEVILLE (CBS13) – Two men have been arrested in Roseville, accused of being connected to a large-scale marijuana growing operation at a residential home.

Police were alerted to the operation on May 7 after a utility worker noticed that a home on Toscano Court was using 16 times the amount of electricity for a home its size and that the home’s electrical box showed signs of tampering, according to a Roseville Police Department statement.

Responding officers spotted a vehicle they described as suspicious and stopped it. Inside were 36-year-old Gui Lin of Sacramento and 56-year-old Jing Xiong You of Pleasant Grove.
