Miriam Masekela was a human female who was the chief of the Starfleet security contingent at the Federation Embassy on Qo'noS. In 2379, the Klingon group Klahb attempted to take over the embassy. During the initial attack, a Klahb member named Krant hit Masekela in the chest with a disruptor set on "burn". She escaped and managed to get to the luxury guest rooms on the sixth floor, but died before Worf was able to get to her. As the invaders knew only that she had escaped, Worf threatened that he and Chief Masekela had already killed several of their members and would capture the rest of them if they did not surrender. In reality, it was Worf alone who retook the embassy.
