Col Muhammad Suwaysi was shot while leaving a meeting in Tajoura, a suburb in the east of the capital.
Two of his colleagues were also taken captive, the interior ministry said.
Libya has been gripped by violence involving militias that spearheaded the 2011 uprising against Muammar Gaddafi. Thousands have been forced to flee recent fighting in Tripoli.
