Pope Francis orders inquiry in sex abuse investigation; 4 priests arrested in Spain

Police in Spain on Monday arrested four Catholic priests accused of sexually abusing children in the southern city of Granada, the interior minister said.

The arrests came a week after a 24-year-old Spanish man wrote to the Vatican alleging a group of priests molested him as a boy as well as other children. "Police this morning arrested four priests implicated in this affair," Interior Minister Jorge Fernandez Diaz told reporters.

Judicial sources last week said that courts had launched an investigation targeting 12 people. The Archdiocese of Granada said it suspended several priests and sent the conclusions of its own internal inquiry to the Vatican, acting after the young man's letter.

Media reports said Pope Francis ordered an inquiry into the archdiocese and telephoned the man directly to apologise on behalf of the church. The Archbishop of Granada Francisco Javier Martinez and other clerics on Monday, prostrated themselves on the floor during a mass in a gesture of apology to the victims of abuse.

After a series of paedophilia scandals in the church over recent years, Pope Francis has taken a zero-tolerance approach since taking over in 2013 from Benedict XVI.
