I don't understand why so much of that short extract of CCTV footage is of nothing happening. It's almost as if the police aren't even trying.
If I'm reading the comments on the ITV page correctly they've onlu just identified the three young people today. That's surprising to me as it looks from their clothing that they've come from work. IMO it wouldn't be hard to go to the local late night places and see which one has a uniform top like the people seem to be wearing.
There is also a comment that suggests that people viewing the footage today spottted someone the police hadn't seen themsleves although that may just be unclear wording by the poster.
I hope it's OK to refer to comments on an MSM facebook page
Running man doesn't loomk suspicious to me, just someone in a hurry or cold or wanting to get out of a desterted area maybe
