From The Guardian:
Socialist bookshop Bookmarks has said that it has been inundated with messages of support after far-right protesters targeted it in an attack on Saturday evening.
Twelve men, one of whom was wearing a Donald Trump mask, entered the central London shop as staff were closing for the day, knocking over displays and ripping up magazines while chanting far-right slogans. The shop, which is planning a free public “solidarity” event with appearances from authors on 11 August, said it had received messages of support from MPs and writers as well as thousands of activists from around the world.
Noel Halifax, who was one of the two staff in the shop on Saturday evening, said: “There were a dozen of them bellowing and saying that ‘we are this, that and the other and it’s a disgrace’. One was saying something like, ‘We wish you burn down’. There were two of us, a dozen of them. I’m 67, there’s no way we [could] shove them out of the shop,” he said.
“They were very shouty, bellowing in your face, saying incoherent things. The books they were holding up and what they were saying about them made no sense. They grabbed hold of a book called Posh Boys, which is about how public-school boys still run Britain, and accused us of being paedophiles for selling this book, saying, ‘You like boys, don’t you.’ That sort of nonsense. They’d clearly been on a demonstration, because their placards were nothing to do with us. They were attacking the BBC, and they were wearing baseball hats saying Make Britain Great Again. One had a mask, oddly enough a Trump mask. I thought anti-Trump people wore Trump masks.”

Halifax described the support Bookmarks had received after the attack as overwhelming. Members of the public have been donating money to replace damaged stock and help increase the store’s security, while names including singer and activist Billy Bragg and MPs David Lammy and Rupa Huq have been vocal in their support online. “The normalisation of far-right politics is already leading to chaos and vandalism on our streets. Fascist thugs attacking bookshops is the logical conclusion to a political movement that rejects facts and experts. We need to be vigilant,” Lammy tweeted.
Dave Gilchrist, manager of Bookmarks, said: “This horrific attack on a radical bookshop should send shivers down the spine of anyone who knows their history. The Nazis targeted books because they knew how important radical ideas are for challenging racism and fascism. The same is true today, and that is why we have to show that we won’t be intimidated.”

PG thoroughly condemns any sort of violence directed towards any legal business, especially a bookstore.
However, one detail mentioned in the OP tickled his Spidey-sense. Although all PG knows about violent far-right British protesters is what he reads online, the Donald Trump mask detail struck him as strange. Do violent far-right British protesters think of Donald Trump as their hero? PG can think of a lot more likely heroes for this type of mob.
The Trump mask immediately brought a false flag operation to PG’s mind (perhaps the result of either too few or too many Diet Cokes consumed today).
To refresh the recollection of some visitors to TPV:
A false flag is a covert operation designed to deceive; the deception creates the appearance of a particular party, group, or nation being responsible for some activity, disguising the actual source of responsibility.
The term “false flag” originally referred to pirate ships that flew flags of countries as a disguise to prevent their victims from fleeing or preparing for battle. Sometimes the flag would remain and the blame for the attack laid incorrectly on another country. The term today extends beyond naval encounters to include countries that organize attacks on themselves and make the attacks appear to be by enemy nations or terrorists, thus giving the nation that was supposedly attacked a pretext for domestic repression and foreign military aggression.
Operations carried out during peacetime by civilian organizations, as well as covert government agencies, can (by extension) also be called false flag operations if they seek to hide the real organization behind an operation.

On the other hand, PG could be entirely wrong in his musings. Such errors have definitely happened before.
