Stolen bikes

So I'm back from a 5 hour stake-out of Bricklane market earlier this morning. . . . . .
A couple of months ago we had several saddles stolen from bikes parked outside the office. One of the victims, Anna, phoned the police on 101 and reported it to the cycle task force. She also got the images from the landlord's cctv.
The next Saturday she went to Brick Lane early and saw someone with the same rucksack as in the cctv, selling saddles to stallholders. She phoned the police and the guy was arrested, she got her saddle back.
When all the police processes are complete she will write it up on our website. It worked for her because she could positively identify the saddle and had already reported it to police before visiting the Lane.
