More than 1,900 marijuana plants were seized and 17 people were arrested during law enforcement operations in San Bernardino County, authorities said Wednesday.
Investigators served six search warrants in Landers and Yucca Valley as part of the operations, the San Bernardino County Sheriff's Department said.
Investigators also confiscated 110 pounds of processed marijuana.
At one site, 378 mature and budding plants up to 5 feet tall were growing on a 1.5-acre plot, authorities said. Three suspects were arrested.
"The amount of marijuana seized at this location was not consistent with personal use and suggests the suspects had no intention abiding to the state's medical marijuana laws," department authorities said in a statement.
The investigations are ongoing and anyone with information is asked to call authorities at (909) 890-4840.
