“The estimate of the narcotics seized was $19,664,000,” said Lt. Andrew Mathes.

On top of that, police also seized nearly $150,000 in cash, pre-made money orders, an assault rifle and three handguns.

The raid happened on the 800 block of San Julian in the Flower District of downtown L.A.

Detectives say the operation was a processing facility.

Police say 24-year-old Daniel Ontiveros and three other men were arrested.

Even though marijuana is legal in California, it’s unclear if the narcotics were safe.

“Our goal is that anything that is being consumed has been regulated and an approved product,” said Lt. Mathes.
