Same thing happened to me about 7 years ago when I lived in London. Someone picked up the MC28 and stuck it in the back of a van. I'm guessing the smartcard flumoxed them as they dumped it about two miles away. They had cut through all the wires and tried to twist em all together in the vain hope it might start. When that didn't work they screwdrivered open the fuel cap and tried to set fire to it. Thankfully they couldn't even get that right!!
Take my hat off to the police, they called me before I had reported it. I've had two other bikes stolen since then, not a nice feeling.
Good luck gettin your scoot back on the road.
