ALTOONA — The bishop of a central Pennsylvania diocese has apologized and promised reforms after the state attorney general released a scathing report on clergy sex abuse of children and created a hotline seeking more accusations.

The hotline has fielded more than 100 calls since Attorney General Kathleen Kane on Tuesday said two former bishops either covered up or didn’t do enough to respond to hundreds of abuse allegations in the by more than 50 priests in the Altoona-Johnstown diocese from 1966 to 2011.

Bishop Mark Bartchak called a Thursday news conference to apologize and promise to reform the diocese’s training and background check program and the review board that vets allegations of clergy abuse.

The bishop says he’ll deliver a special message to parishioners this weekend and schedule special prayer services in the coming weeks.
