A cab driver lost cash and two cell phones after a pair of customers held him up on Harrison Circle during a late-night robbery earlier this month. 

The driver picked up the duo near the alleged robbery, police said. Not long after he let them into his cab, about 11 p.m., June 16, one of the men pressed what felt like a gun to the back of his head, officials said.

He never saw the firearm, but turned over his valuables. The two men then fled on foot along the 900 block, leaving the driver unharmed. They remain at large, said Ashley Hildebrandt, department spokeswoman, and the investigation is ongoing.
