Thanks guys for your replies. Last friday i put a notice in the back window of my van that said "name" of "address" owes me £250.00. i then texted them a photo of it and drove up and down thier street a few times .Over the weekend i parked the van outside the entrance of the supermarket which just happen to be a very short distance from thier house. Yesterday (monday) three police officers turnd up to arrest me under the public order act section 5 , after much disscussion they pursuaded me to remove the poster end promise not to do it again . I am cosidering doing it again and going to court just imagine the local press ....
