# All law enforcement agents who suspect that a person who has been arrested is in violation of immigration laws must investigate the detainee's immigration status, and if they find evidence of illegality they must report it to the attorney general of California, and to the federal Immigration and Naturalization Service ( INS ).

They must also notify the detainee of his or her apparent status as an alien.
