LONG BEACH, Calif. (AP) — Authorities say four people were arrested after about 16 tons of marijuana was found in storage containers at a Long Beach plant nursery.

Los Angeles County Sheriff's deputies serving a search warrant made the discovery Thursday at Rolling Hills Nursery on Orange Ave.

The Long Beach Press Telegram says the pot is valued at $150 million to $300 million, depending on the quality.

Sheriff's narcotics investigators made the bust with help from other local law enforcement agencies including the Long Beach Police Department.

Officials did not say what charges those arrested might face.

The investigation is ongoing.
