NEW BEDFORD, Mass. (AP) – A Massachusetts leather-goods factory raided in 2007 by immigration agents will close.

Minneapolis-based military contractor Alliant Techsystems said Friday that the factory will shut down by July 31. The plant employs more than 300 people, mostly Latinos.

Federal agents raided the plant and arrested more than 360 undocumented workers in 2007. The owner sold it to Eagle Industries soon afterward.

Eagle Industries, based in Fenton, Mo., was acquired by ATK in March. ATK said the factory was operating well below capacity.

But U.S. Rep. Barney Frank called the closure “absolute corporate savagery” and said it makes ATK “unfit” to continue as a U.S. contractor.
