Ending a sexual abuse case in which Pope Francis intervened three years ago, a Spanish court on Tuesday cleared a parish priest in Granada who had been accused of molesting an altar boy.

The court found no evidence that the Rev. Román Martínez had sexually abused one of his former altar boys more than a decade ago.

An investigation began after David Ramírez Castillo wrote to Pope Francis in 2014, detailing the sexual abuse that he said he and others suffered repeatedly when they were teenagers at the hands of a group of priests led by Father Martínez.

Pope Francis phoned Mr. Ramírez Castillo and urged him to pursue his complaints. The pope also ordered a church investigation into the case, demanding complete transparency.
