Two supposedly “legitimate” businesses raided Monday afternoon after a tip about drug lab operations at two locations, authorities found hash-oil labs operating at those locations
Pasadena Police called in support via the LA Impact, an interagency support drug task force.
Note: At around 7pm you could see some of the LA Sheriff officers around Pasadena, most likely involved in the raid.

The business names and owners have not been released, which is odd, but wee do know that one location was at the 2500 Block of Nima St, which is off Altadena Drive North of Colorado in East Pasadena, a commercial/industrial area with auto mechanics.

This is a street view of the approximate area.
