LOS ANGELES—California’s biggest legal marijuana grower said nine of its employees were detained in a federal immigration raid last month that netted hundreds of arrests, and that the business has ended its relationship with two labor contractors that supplied its farmworkers.
The statement came nearly a month after federal authorities raided Glass House’s farms in Camarillo and Carpinteria, northwest of Los Angeles, and arrested about 360 people. Federal officials characterized the raids as one of the largest immigration operations since President Donald Trump took office in January.
