Other officials familiar with the matter could not immediately be reached.
Initial investigations showed the women were promised jobs as maids in homes and hotels with a salary of $1,000 a month, but instead forced to become "sex slaves" to pay off travel fees and other costs of $7,000.
The US Department of State said in its 2011 report that Uganda "does not fully comply with the minimum standards for the elimination of trafficking." It cited Denmark, Oman, and Malaysia as destinations for Ugandan victims. list of countries with the worst human trafficking records for a third time - meaning it faced possible sanctions unless its record improved.
Malaysia has often been under the spotlight for human trafficking. In 2010, Malaysia was upgraded to a "watch list" after authorities stepped up anti-trafficking efforts.
Kampala, Uganda: Advertisements pinned on the walls of shopping malls in Uganda's capital promise young women a free ticket to a well-paying job in Malaysia as a nanny, maid or bartender.
Instead many are forced to become "sex slaves" to pay off travel fees and other costs amounting to as much as $7,000.

Authorities say nearly all of the prostituted girls have college degrees but have failed to find jobs in Uganda, where unemployment is high.
And Ugandan officials say it is hard to cripple a highly organized syndicate that preys on educated but vulnerable women, and then intimidates them into the kind of silence that hampers investigations."Some of the girls, when they reach here, we ask them to tell us what happened.
And she says, 'I can't tell you; I will die.' They will never talk," said Asan Kasingye, chief of Interpol in Uganda.
