Emanuele Pozzolo’s gun allegedly accidentally went off and slightly wounded the son-in-law of both a party member and Justice Undersecretary Andrea Delmastro’s bodyguard at a New Year’s Eve party.
The incident does not have any bearing on the government.
Pozzolo, who owns the gun but says he did not shoot it, has been placed under investigation for grievous bodily harm after the bullet grazed the thigh of the 31-year-old.
He took a gunshot residue test the day after the incident, whose result has yet to be made public.
Pozzolo used his parliamentary immunity to refuse the confiscation of his clothing.
There have been opposition calls for Pozzolo to resign or for Meloni to fire him.
Pozzolo has in the past posted on social media photos of Mussolini, and said he is a “reactionary” who is in favour of “defending ourselves with firearms”.
