Sacramento Police were called out to reports yesterday afternoon of a man on a rooftop -- with a rifle. 

That call led to police arresting three people in total.

No one has been officially identified, but News10 is reporting a 32-year-old man was arrested yesterday afternoon after fleeing from officers. He's facing gun charges. No word yet as to why he was carrying a rifle while atop a roof. 

At the same time, an 18-year-old man and a woman were both arrested, as well.

The man faces charges for harboring a fugitive, and the woman was busted for some felony warrants.

We should be getting more details about this incident when officers finish their investigation.
