Lost Bag at Oct Critical Mass

Hi all. My pannier bag went missing at Jackson's Boat after the Halloween Critical Mass last Friday. It had about £250 worth of stuff in it including phone, bike lights, helmet, hi-vis jacket, tools, prescription sunglasses, gloves and beer. Rather than thinking a fellow cyclist would sink low enough to steal within their own community, I'm hoping that it might have been picked up by accident or something. If anyone saw anything then please let me know. I've been trying to phone the pub but no one answers the phone. There was a group of punk-looking people sat next to us but they'd gone by the time I noticed it was missing so I didn't get a chance to ask them if they'd seen anything.
Please get in touch if you saw anything. Maybe you saw some people leaving hastily with a pannier bag, or emptying it out, or generally looking suspicious! Did you see anyone drinking cans of Grolsh or eating a big yummy galaxy chocolate bar?
