LINCOLN, Neb. (AP) — A prosecutor says charges no charges will be filed against a University of Nebraska-Lincoln fraternity president who was accused of tampering with witnesses in a sexual assault investigation.

Lancaster County Attorney Joe Kelly said Friday that his office will not file charges against Delta Upsilon Fraternity president Timothy Kubert. He was arrested May 6 and has since been released.

Kubert was accused of telling fellow members not to talk to police about a sexual assault reported April 5 at the frat house.

Kelly said — in his words — “The language used didn’t amount to a crime, tampering with a witness or otherwise.”

Kelly says the sexual assault remains under investigation.
