SFAppeal has word that the above (alleged!) bike thief was caught cutting bike lock cable thingies on Market near Fifth Street yesterday. And just who caught him? Members of the SF Bike Coalition who were frolicking about during their "Ice Cream Sunday Ride."

Oops.

Naturally, the SFBC folks were none too thrilled when they came across a bike theft in progress, giving way to a chase and some great shots of the unidentified man. According to Appeal, Program Manager Marc Caswell noticed the guy using "2 foot long bolt cutters attacking the cable locks on some bikes parked in front of the [Westfield Mall]." OMGs and WTFs were exchanged, a cigarette was spit at someone, brows furrowed, and a chase ensued. The guy wasn't caught, but you should keep an eye on your cycling mechanism of choice if you see his glamorous mug nearby.

Grab some popcorn, and check out more pics of the chase.
