A bishop acquitted of raping a nun has resigned as leader of the Catholic diocese in an Indian city.

Pope Francis accepted the resignation of Franco Mulakkal, 59, who was bishop of the Jalandhar Diocese in the northern state of Punjab.

The Vatican did not provide a reason for the resignation or why Francis accepted it.

The normal retirement age for bishops is 75.

The nun accused Mr Mulakkal of raping her multiple times during his visits to her convent in Kuravilangad in Kerala state, in a case that became a major issue amid allegations of sexual abuse in the church.

Police charged Mr Mulakkal with rape, illegal confinement and intimidation of the nun.

A group of fellow nuns launched unprecedented public protests demanding Mr Mulakkal’s arrest in 2018.

He was detained and soon released on bail.

A court acquitted Mr Mulakkal last January.

The nun has appealed the verdict to Kerala’s High Court.

Mr Mulakkal was the official patron of the nun’s community, the Missionaries of Jesus, and had influence over its budgets and job assignments.
