SIOUX FALLS, S.D. (KELO.com) — A elderly man, armed with a cup of gasoline, is accused of robbing a Sioux Falls casino near 8th Street and Franklin.

Police say the 70-year-old man throws the gas on the clerk and threatens to set her on fire if she doesn’t give him the cash.

Larry Lee Fletcher is arrested only hours later at a motel. Police use evidence from surveillance video to quickly make the pinch. He’s wearing the same shoes seen in the video and the coat he was wearing during the robbery is found in the room.
