A spokesperson for Blackpool Police said in a post to their Facebook page today: "We want to speak to Paul as we think he can help us investigating a case where a large quantity of cannabis was found when we stop checked a vehicle in December 2016.
"Paul has been a little bit sheepish and has been refusing to answer our calls to arrange a voluntary interview so we thought about asking for a little bit of help to find him. Unfortunately he has moved on from the address we have for him."
