A couple of years ago one of mates who is a carpenter had his ute/work trailer park in his driveway and one night he caught some kids from a neighbouring suburb trying to steal it. He knew that if he called the police these kids would just cause further problems for them, so he got them to call their parents a 1am and to come and collect them. (Luckily the parents had half a brain)
He made it very clear to both the kids and parents that stealing someone’s car is one thing, but these kids tried stealing all his tools which is his lively hood and that is unforgivable. So he told them to spread the word that if he ever catches them or any of their mates around his house or tools ever again, then will use his nail gun on them and then use his array to tools making some alterations to their family home.
Rest of the suburb had ongoing problems, but he ever had a problem after that.
Hope you get your trailer and tools back.
