The elderly gentleman in the video is Luigi Fogli, a businessman in his 80s, who runs a hotel (Hotel Lory) in Ficarolo, in the province of Rovigo. Not long ago, he inquired about providing asylum accommodation services from the local government, but chose not to pursue the matter further when he found out that he would only be paid 7 euros per "refugee" per night. At that point, the local prefecture simply confiscated his hotel and forced the invaders upon him.
He tried to block their admission and, in fact, managed to hold it up for a few hours. But, eventually, he succumbed and the invaders arrived. Apparently he fainted at some point during the proceedings.
Things like this are going on all over Italy. The local authorities are confiscating hotels and using them as invader accommodation. In some places, as in the incident described above, the proprietors resist; in other cases they cooperate and defence is left to the local citizens.
Here is a picture from a similar incident in Verona. The hotel Castello had been confiscated (link) but locals were happy and set up barricades.
The mass confiscation of property to host "refugees" has provoked mass protests in Verona and given rise to the "Verona ai Veronesi" [Verona for the Veronese] movement. Here are some videos of their recent protests.
