Frederick County authorities have filed child abuse charges against a retired Catholic priest for alleged offenses against an altar boy in 1976. Monsignor Thomas Bevan, 73, of Cascade was released on $25,000 bail Thursday. He was indicted on two counts of child abuse Jan. 22 but the charges were kept sealed until Thursday, when an arrest warrant was served. Assistant State's Attorney Lindell Angel says Bevan sexually abused a 10-year-old boy in 1976 when he was associate pastor of St. John the Evangelist Catholic Church in Frederick. The Archdiocese of Baltimore says Bevan denied the allegations when confronted by church officials in August. The archdiocese removed Bevan in August as pastor of the Church of St. Patrick in Cumberland.
