If they're asking questions at the end of Beverley road that meets Clough road then I wonder Could it be linked to whatever they wanted the Croda CCTV witnesses for? Maybe they've come forward? If any of those 4 turned right they'd reach Beverley road - is that correct? Which brings us right back to those 4 and that time frame between an hour and two and a half hours after Libby was last seen. I don't think any of them are PR. I've always assumed they're linked to the police searches of Oak Road Park somehow but would getting to the Humber from that southernmost part of HU5 be possible? Is it near the quay that people have mentioned? Is there a way of getting to near the Deep without being seen .
