Deputies served a search warrant Thursday morning in the 7200 block of Madison Street and found several thousand marijuana plants in various stages of growth, Los Angeles County sheriff’s Capt. Keith Swensson said.

“Officials from the city have deemed the location unsafe, and red-tagged the building due to numerous electrical code violations found,” Swensson said.

A follow-up investigation will be conducted by members of the sheriff’s Narcotics Bureau.
