RAPID CITY, S.D. (AP) — Rapid City police are investigating another armed robbery at a casino.

The holdup late Sunday morning is the fifth in the city in two weeks.

Authorities say a man entered the Chance's Casino through a back door about 11:30 a.m. Sunday, approached the counter brandishing a pistol and demanded money.

The man fled on foot with an undisclosed amount of cash.
