A criminal case that had raged for more than two years against an alleged Libyan arms dealer came to an abrupt end on Monday after a federal judge ordered the Obama administration to produce documents related to the “covert transfers of weapons” to rebels in Libya between 2010 and 2011.

The charges against Marc Turi, a defense contractor operating a company called the Turi Defense Group, had threatened to expose the administration’s alleged direct involvement in providing weapons to Libyan rebels fighting against Moammar Gadhafi, the former leader of Libya who was ousted in 2011 with the help of the U.S. military.
