Portland police say a robber used a syringe to threaten workers at an ice cream shop by claiming the needle was "full of AIDS."
Officers went to the Baskin Robbins on Southwest Broadway just before 9 p.m. Tuesday.
Employees told officers a man entered the store and pulled out the hypodermic needle, saying that it was infected.
The man was able to take off on foot with an undisclosed amount of cash.
No one was hurt.
The robber was last seen walking northbound on Broadway.
Several officers searched the area but were unable to find the robber.
He's described as a white man in his 20s, 5'9" tall and skinny with short brown hair and glasses.
Police say he was wearing all bright colors at the time of the robbery.
There's no word from police if they were able to recover the allegedly infected syringe.
Anyone with information about this incident is asked to contact robbery detectives at (503) 823-0405.
