Simon Cho speaks at a news conference on Friday, Oct. 5, 2012, in Salt Lake City. Cho said Friday he agreed to a coach's demand to tamper with a Canadian rival's skates last year after the command was made a third time and in Korean by Jae Su Chun. Cho's comments confirmed several allegations made in the arbitration demand that seeks to permanently remove U.S. coach Chun. Chun has denied any wrongdoing but is suspended.

KEARNS, Utah — Another speedskating assistant coach has been suspended for failing to report the skate tampering by Olympian Simon Cho.

Investigators, however, say there wasn't evidence to support allegations U.S. short-track coach Jae Su Chun engaged in a pattern of physical or emotional abuse.

U.S. Speedskating officials announced their findings Friday at a news conference at the Utah Olympic Oval.

Spokeswoman Tamara Castellano says interim coach Jun Hyung Yeo has been suspended. Chun has denied abuse allegations as well as charges by Cho that he ordered the reigning national champ to sabotage a Canadian's skates during the 2011 World Team Championships.

Cho confessed to the tampering earlier Friday.
