Posting on behalf of a friend. Don't know the full details of the bike, I've only seen the photo that I'll try to attach here, but looks like a pink mixte, drop bars with fraying white bartape.
Apparently had a flat on the way home, so locked it at the tramstop on Royal Pde before Princes Park overnight, and returned the next day to find it missing.
Only got a photo I pinched from Facebook, hope it works:
PM me if any news.
