The Catholic Archdiocese of Philadelphia, battered since 2011 by a high-profile child sex abuse scandal, said on Sunday it had placed another five priests on administrative leave, including one accused of sexual abuse. Following a church investigation Archbishop Charles J. Chaput determined that there was a substantiated case of sexual abuse of a minor against a 58-year-old priest identified as Michael A. Chapman, according to a church statement. It gave no further details on the allegation. Chapman was not immediately available for comment. The other four suspended priests were determined to have violated standards of behavior and boundaries, the church said without elaborating. A church document defines one of the boundaries as pertaining to appropriate behavior with children. The church said it had already reported the allegations against the men to the Philadelphia district attorney's office, and an archdiocese spokesman said he was not aware of any criminal charges against the men. Calls to the district attorney's office were not immediately returned on Sunday.
