Both victims said the gunman approached them at 1:30 a.m. Sunday at Main and Harding avenues and demanded "certain property," Detective Lt. Robert Bracken said.
Moments later, he fired a shot and the driver sped off, he said.
No one was injured, Bracken said.
The victims described him only as black and in his 20s.
