AMES, Iowa (AP) — University leaders have determined there's not enough evidence to pursue charges stemming from allegations that University of Iowa marching band members were targets of abuse during last season's football game at Iowa State University.

Members of the Hawkeye Marching Band allege that they were subjected to racial slurs and other verbal abuse as well as sexual harassment before, during and after the Sept. 14 contest at Jack Trice Stadium in Ames.

Iowa Board of Regents President Mike Richards said in a news release Wednesday that the two universities' presidents, lawyers and police chiefs had discussed the investigation and decided not to seek charges.

Presidents of the University of Northern Iowa and the two other schools have agreed to work together in reviewing and improving game management policies, Richards said.
