My brother had a similar thing happen a while back. Black unmarked bmw pulled out and started following him for a while, as he was getting closer to the house they were still following. Wasnt keen on letting some random person in a black bmw follow all the way home sitting far too close so accelerated off and lost them. They must have had the address off the plate, pulled in to the drive so meanwhile my brothers walking to the garage to grab something and out steps 2 police officers!!! After them 'having words' he made the point that if there was an issue they should have pulled him over straight away or made clear they were police.
