On the heels of major shows of force by federal immigration agents in Southern California, a judge is set to rule in a lawsuit seeking to halt immigration raids in Los Angeles.

Federal immigration authorities said Friday they arrested about 200 immigrants suspected of being in the country illegally in raids a day earlier on two California cannabis farm sites. Protesters engaged in a tense standoff with authorities at one of the farms during the operation.

Authorities executed criminal search warrants in Carpinteria and Camarillo, California, on Thursday, the Department of Homeland Security said.
