I've got a neighbour exactly the same.
He shipped off his sons to Pakistan a few years ago, do they could get a "become Islamic scholars". I imagine he'll bring those radicalised kids back here now.
He also moved with them, leaving his wife and daughter here, but was listed as living here on Companies house.
He makes everyone's life hell, by being the only with a drive, but parking his untaxed, un MOT,'d taxis on the few parking spaces for everyone else.
We have a lot of Muslim neighbours who are diamonds, even they've had run ins with him, but he refuses to even look at us women who've challenged him, he literally refuses to speak to us.
