Newark’s Mayor and a Democratic Congresswoman for the district hit out at Immigration and Customs Enforcement after they said agents raided a business in the New Jersey city to detain undocumented residents without producing a warrant.

Newark Mayor Ras J. Baraka issued a statement late Thursday afternoon denouncing the raid as an “egregious act” conducted without a warrant and in violation of the Fourth Amendment of the U.S. Constitution, which guarantees “the right of the people be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures.”
