Police arrested a 19-year-old man for allegedly sexually assaulting a minor.

An Oahu grand jury returned an indictment July 31 against Seth Owens, charging him with two counts of first-degree sexual assault and three counts of third-degree sexual assault involving a girl younger than 14 years old.

Authorities arrested him Tuesday night on a $50,000 grand jury bench warrant.

Police said the victim reported on June 16 to a family member that an acquaintance of her older brother had sexually assaulted her.

Police initiated an investigation after they were notified of the assault.
