With five unsolved strong-arm robberies in December and January, police have asked for the public's help in tracking down information about the man or men responsible.
Photos of the robber in three of the incidents were distributed Thursday.
The robberies happened between Dec. 19 and Jan. 28, and four of the five were at businesses on or near New Bern Avenue, police said.
A strong-arm robbery involves threatening or using physical force, but no weapon is involved.
In each case, police said, a man entered alone, took money and was last seen leaving on foot.
