The trees are over 30 metres from his house so there is no request to prune the roots. He is just doing it to be awkward. He is about 90 and has nothing else to do than pursue me. He called the police out as well, the amazing thing is that they actually responded and came out! I guess there is not much esle going on in rural france, they were a bit embarrassed when they got there and realised it wasnt really a police matter :)
