. It was parked on a well lit, good residential area in North London (Camden borough), just in front of my house. They chopped it off by using probably an electric sabre saw (I guess). It's too late for me but I hope this message will help other fellow Bongoers in the area.
Unfortunately there was no CCTV nor witnesses (as far as I can tell), but it doesn't seem it would have made a difference. There are plenty of youtube videos of catalytic converters being stolen in full daylight with people recording the action with their phone cameras, and the thieves couldn't care less. Nor it seems the Police cares much either about this kind of thefts (or can do much about it).
After doing some research online, it seems that the only option is to make it really hard for them to cut it off by covering it with a steel metal plate or wires. This probably won't save you from really dedicated thieves but it will buy some time and hopefully deter them in first place.
I wish you will be luckier than I was!
