A man involved in an armed standoff with police in the South Dakota city of Parkston faces new charges.
Authorities allege 18-year-old Nicholas Heisinger barricaded himself in an apartment on March 2 and held police at bay for about two hours before surrendering without incident.
He initially was charged with simple assault on a law officer and obstructing law enforcement. He now is charged with felony aggravated assault of a law officer, obstructing law enforcement and public indecency for allegedly being naked in public.
He could face up to 25 years in prison if convicted on the felony assault charge.
