SIOUX FALLS, S.D. (AP) — Sioux Falls police are investigating home invasions on two consecutive nights.

Authorities say three people reportedly forced their way into a Sioux Falls residence, assaulted an occupant with weapons and stole cash early Tuesday and again early Wednesday.

The Argus Leader reports that police have no suspects, and without good descriptions of the attackers they don't know for sure whether the same three people are responsible for both attacks.
