Rome: Italian police have raided the home of an influencer whose affair with the country’s tourism minister brought about his political downfall, with officers seizing a pair of “spy glasses” which she used to film inside parliament.

Maria Rosaria Boccia is under investigation for allegedly making threats to Gennaro Sangiuliano, who was forced to resign over their affair earlier this month.

The exact nature of the alleged threats has not been made public by prosecutors, but under Italian law it is an offence to make threats to a public official or politician.

Police raided her home in Pompeii, the modern town adjacent to the World Heritage ancient Roman archaeological site, seizing her computer, mobile phone and a pair of “spy glasses” that she used to record video of herself walking through the corridors of power in the lower house of parliament in Rome.

The influencer and fashion entrepreneur subsequently uploaded the video to social media, breaching rules that forbid visitors from recording video and audio inside parliament. She was subsequently banned from entering parliament for making the recordings with the Ray-Ban Stories smart glasses which are equipped with a tiny camera and microphone.

Boccia is also under investigation for alleged assault, amid accusations that she hit the minister and left him with an injury to his head.

Before his resignation, he appeared at events in public with a large strip of plaster on his forehead.

The relationship between Sangiuliano, 62, and Boccia, 41, appears to have ended acrimoniously in July.
