A Humboldt man is charged with rape and other crimes in an incident involving his live-in girlfriend.

Captain Paul Niedringhaus of the Minnehaha County Sheriff's office says 41-year-old Michael Allen Olson was arrested on Saturday after the woman reported she had been assaulted two days earlier.

He says the alleged incident occurred Thursday evening at the apartment in Humboldt where Olson and the woman have been living.

Niedringhaus says Olson is charged with second-degree rape, domestic aggravated assault and simple assault-domestic.

Olson was to be arraigned on the charges Monday afternoon.
