Stolen bikes

Just had a call from a friend on Englefield Road, he's just seen a sketchy looking dude, hood up, dirty tracksuits, riding unclipped/dangerously on a dark blue/purple frame, black trick forks, risers and gold deep section rims.

Anyone lost/heard about anything?

I've seen this bike (or very similar looking) in clisold park yesterday (sunday) around 16-17, guy had velcro staps on the pedals, but did't used them, what it was intresting way to do it :)
maybe it's a same guy you saw, huge tracksuit bottoms on, but didn't had a hood on, so he had very short blond or ginger-ish hair, pretty young looking too.
