US coach Chun is accused of abuse

Five 2010 Olympic medalists — Allison Baver, J.R. Celski, Alyson Dudek, Travis Jayner, and Jordan Malone — and other current and former members of the US speedskating team have accused head coach Jae Su Chun of ‘‘unchecked’’ verbal, physical, and psychological abuse. The Chicago Tribune and Salt Lake Tribune report that 19 athletes filed a wide-ranging grievance against US Speedskating and 14 signed a complaint with the US Olympic Committee. Attorney Edward Williams, who represents the skaters, said the abuse was ‘‘outrageous.’’ The code of conduct complaint accuses Chun of slamming an athlete against a wall and repeatedly hitting him, throwing bottles and chairs at skaters, and repeatedly telling female skaters they were ‘‘fat’’ and ‘‘disgusting.’’ Williams said the current national team members are boycotting US Speedskating rather than have any contact with Chun and two assistants.
