Lawyers representing four Indonesian fishermen say they were beaten and trapped on vessels that were part of the global supply chain that provided tuna to Bumble Bee Seafoods.

In a lawsuit filed in California, the plaintiffs said that Bumble Bee Foods was aware of and benefited from abuse by suppliers. The company declined to comment.

A group of four fishermen from Indonesia, co-counseled by attorneys for NGO Greenpeace USA, have sued Bumble Bee Foods, claiming they experienced forced labor and human trafficking while working on fishing vessels supplying the company.
