Italian Deputy Prime Minister Matteo Salvini has called for people convicted of violent sexual offences to be chemically castrated, following a horrific incident last week when a group of Egyptian migrants were arrested on suspicion of gang raping a 13 year old schoolgirl in a park.

The Italian newspaper Il Giornale reports that the girl and her boyfriend were attacked in the Sicilian city of Catania by the migrant gang who then dragged the girl into a public bathroom and brutally assaulted her in front of the helpless boyfriend, who they also beat up.

The pair somehow managed to escape, but not before two of the migrants had raped the girl, according to the report.

Six of the migrants, three of whom are minors, were arrested the same evening, with the seventh detained the following day after appearing to attempt to flee the town.
