PORTSMOUTH, Rhode Island — The chancellor of Portsmouth Abbey School has resigned over what the school calls "conduct inconsistent" with its expectations.

The Providence Journal reports (http://bit.ly/1OuGWkw) the school sent a letter to the Portsmouth Abbey community May 12 that said the Rt. Rev. Dom Caedmon Holmes had departed after "his acknowledgment of personal struggles" involving conduct inconsistent with "Benedictine ideals."

The school says it has no knowledge that Holmes' conduct affected any students, but it has retained an independent law firm to "review the situation." The letter provides no further details.

Assistant Headmaster John Perreira says the school hasn't received any allegations of sexual abuse.

Holmes was selected as the school's third abbot in 2007.

Portsmouth Abbey School is a coeducational, Catholic Benedictine boarding and day school for students in grades 9-12.
