Police said all they needed to find marijuana growing in a Van Nuys warehouse was a sense of smell.
Authorities say someone reported an unusual odour at the warehouse on Roscoe Place on Monday. Police and a Fire Department hazardous materials team were called and found more than 200 marijuana plants inside.
Detective Robert Holcomb says the odour coming through a window was so strong that arriving officers recognised it immediately.
The plants were being grown hydroponically, or without soil.
Holcomb says the pot had a street value of about $100,000 (Dh367,315). Six weapons were also seized.
