Damn I literally live behind there

I was there till 18:00 yesterday and then I saw something happened on Facebook but we are yet to find out, when was that posted

17:59

It does say “bomb treat” and is signed off with a wink. Maybe it’s a rather unfunny but trying to be funny reference to the spoof brown signs that have been appearing?

I tried to look at the Facebook group but it appears to be one of those private members only things. Unless I was looking at the wrong group?
