A 35-year-old Sioux Falls man is in jail for allegedly holding a woman captive for more than a month.
Dan Armstrong is charged with a long list of crimes including rape, aggravated assault and kidnapping.
Police caught up to Armstrong after a standoff on the 100 block of North Covell Avenue Friday afternoon. Authorities say the woman was held against her will because Armstrong was worried she'd turn him in.
Armstrong's arrest on Friday was connected to warrants in a separate case.
