LANSING, Mich. (AP) - The Catholic Diocese of Lansing says it has removed a senior priest from public ministry because of what it calls a "credible allegation" of inappropriate sexual behavior with a minor dating to the 1960s. The diocese announced Friday it had taken the action against the Rev. Joseph Aubin, who was not assigned to a parish since he was on senior status. A residential phone listing for Aubin in the Lansing area rang busy Friday afternoon and he could not be reached for comment. The diocese announced in September that it plans to invite an external agency to review how it handled sexual abuse allegations. Its report has not yet been published. Catholic dioceses across Michigan have surrendered documents to state officials investigating sexual abuse by priests.
