The arrest of more than 100 suspected undocumented workers in Van Nuys has been challenged by a federal lawsuit filed by the American Civil Liberties Union and other civil rights groups. The lawsuit claims Immigration and Customs Enforcement barred attorneys from meeting with those arrested, and asks that a judge order the agency to allow attorneys to represent the workers, the Daily News reported. The arrests were made Feb. 7 at Micro Solutions Enterprises, the manufacturer of computer printer cartridges. No company employers have been charged but the investigation is ongoing, the Daily News quoted an ICE spokesperson. Of the 130 workers detained from the raid, only six suspects are still in custody, the ICE spokesperson was quoted in the Daily News. The Daily News reported the ACLU claimed attorneys were barred as the workers were questioned and charged with immigration violations.
