The principal of O'Dea High School in Seattle has resigned amid accusations of sexual abuse.
Brother Karl Walczak is accused of sexual abuse of a minor during his time as a teacher in another diocese in the early 1970s.
Walczak denies the allegations.
The Seattle Archdiocese owns O'Dea High School.
The Archdiocese said Wednesday that O'Dea school administrators reported last August that Brother Walczak had been called back by the Christian Brothers to assist in resolving a proof of claim filed in the Christian Brother's Institute bankruptcy proceeding.
Vice Principal Jim Walker was subsequently named acting principal.
According to the O'dea website, Walczak was appointed principal last year by Archbishop Sartain.
He taught in Christian Brother Schools in California and was the principal of Damien High School in Honolulu for 10 years, and president of Brother Rice High School in Chicago for 12 years.
O Dea and the Seattle Archdiocese are not involved in the claims against the Christian Brothers.
