The Catholic Archbishop of Dublin removed trainee priests from the seminary in Ireland over claims on the use of the gay sex app, Grindr, and failure of the authorities to properly investigate it.
The move is the latest scandal to hit the Catholic Church in Ireland, after the reports of child sex abuse stretching back decades and of church leaders' complicity in covering them up.
Archbishop Diarmuid Martin said a series of anonymous allegations about a gay sex culture at the Maynooth seminary, where over 50 students are training to be priests, had been compounded by the college authorities' failure to investigate.
There were also allegations that students who had spoken to the authorities had been dismissed from the seminary. The president of the seminary, Hugh Connolly, said no investigation had taken place because there had been no official complaint.
