Police are looking for a man after two others were threatened with a firearm on the mountain.
It happened last night around 11:30 inside a rooming house in the area of West 3rd and Southbend.
Police say a man went into the house and confronted two of the tenants by pointing a black bb gun at them.
The victims wound up tackling the guy and he fell down the stairs.
He took off on foot and is described as white, 18-25 years old, 6'-6'2", with a thin build and brown hair.
It's believed he was drunk as police were told he smelled strongly of alcohol.
