I had mine nicked as well not too far from where it happened to you. It was in front of a new bicycle shop in Taman Megah (near Fu Kua for those familiar with the place), very brightly lit. Went for pasar malam less than 30 minutes, came back and realised that it was gone. It was secured using clips and the black rubbery glue thing. Happened about 3 weeks ago. Looks like they're prowling around the area.
Haven't had the funds to buy replacements, so right now running around with holes in my doors. Most likely gonna buy replicas this time around. How much did you buy yours for?
After this experience, I won't buy used parts anymore where budget permits, coz it could've been stolen from someone else. Bloody hell.
