WEST SACRAMENTO (CBS13) — Police in West Sacramento on Wednesday raided a large indoor marijuana growing operation that involved three separate homes on a single block.

CBS Sacramento reports that West Sacramento police said officers had been investigating the operation for the past few months.

Neighbors started complaining of the smell of marijuana coming from the homes, prompting detectives to look into the operation a little closer.

On Wednesday morning, detectives raided the homes.

“Although marijuana possession and growing marijuana is legal in California, there are stipulations to the law that must be adhered to. The suspects in this case are not residents of our city, they purchased homes for the sole purpose of furthering a criminal enterprise,” West Sacramento said in a statement.

In total, about 2,000 marijuana plants were seized. About $23,000 in cash was also taken as evidence.

Police said several suspects have been arrested, but their names have not been released at this point due to the ongoing investigation.
