He would have fired after the municipal police showed up at his home, ending up lightly hitting a firefighter who was supporting the police.
It happened in the early afternoon in Torre del Lago, in the municipality of Viareggio (Lucca).
Now the man is barricaded in his home where his elderly father would also be found.
From the first information it seems that the shot fired by the man would have been muffled by a door on which he bounced.
