Werner Fajardo, 34, who owns the El Cuervo Bar in Huron, was arrested Saturday on the latest charges, KELO-TV, Sioux Falls, reported.
Huron Police said they found 11 minors inside the bar and five had consumed alcohol.
Fajardo had already faced charges from last week, including three counts of rape.
KELO said bond has been set at $150,000. He had paid $10,000 bond after his arrest last week.
"I was surprised to find that out that so soon after being arrested for a very serious offense that he's in that kind of conduct," Beadle County State's Attorney Michael Moore said.
Fajardo's next court appearance is set for Dec. 14.
