Colorado Spring police late Saturday hunted for a lone gunman who held up The Quality Inn at 555 Garden of the Gods Road.
Police say the robber entered the hotel just before 9 p.m. and pulled a pistol on a clerk while demanding cash.
The robber, a white male standing 6-feet-tall and weighing 150 pounds, fled with an undisclosed amount of money, police said in a news release.
He was last seen walking westbound from the hotel, police.
Officers flooded the neighborhood after the robbery call and used a tracking dog in a bid to find the robber, but came up empty.
Police said they established a perimeter cordon around the hotel within two minutes.
But the robber, with short gray hair, was gone.
