Rome, February 22 - Catholic members of Italian consumer association Codacons on Friday submitted a request to prosecutors to open a sex-abuse investigation into Cardinal Roger Mahony if he comes to Rome for the conclave to elect a new pope next month, but also asked Benedict XVI to prevent him from attending at all. "We maintain there are sufficient grounds to put him under investigation as soon as he enters our country," said a statement from the group. Mahony, the retired archbishop of Los Angeles, must answer questions under oath Saturday about a visiting Mexican priest who in 1987 is believed to have molested 26 children. In its petition to prosecutors, Codacons said "we must bring to light whether there were any Italians who were victimized". Mahony's case has prompted a growing number of calls on social media and from advocacy groups for him to skip the conclave, which is expected to commence mid-March. Codacons Friday asked the pope to intervene. "Considering the requests from the Christian world, keep the cardinal from participating in the conclave," they said.
