Reminds me of a footballers brother who got jailed for shooting a ‘firearm’(bb gun) at the heroin addicts who burgled his house twice in one weekend... to add insult to injury the newspapers reported it as a feud though I think the sentence reflected it was a provoked attack but handled completely wrong.Genuinely feel for you mate. You confront them, or cause them problems, they'll be back when you aren't there.
The only way of dealing with this is the police. Go and speak to them in person.
Thinking about it, you may need to put cameras up, on yours or neighbors properties facing you. Get an ID on the little bastards and see if you can make a civil court case.
