The Catholic diocese of Milan has doubled the number of priests who practice exorcism and set up a hotline to deal with the volume of calls.
In an interview published on a Church-affiliated news website, it said it had increased the number of specially trained priests from six to 12.
It has also published the names and mobile telephone numbers of priests able to deal with such requests.
The number, set up in early November, will run for a few hours each day.
People calling it will be able to book an appointment to see a local priest with specific training.
