Hmm. working as a community is the only way to deal with a few rogues. I have installed cerebus onto my phone today. Will get my wife to install a similar tracker app onto her iPhone:

Will tell police where the phone is, or rather you will via the web site , and also will take photos of the twits.

A gang of teenagers attended to mug me and a friend in Maida Vale last year. Happens everywhere in London. I know that is small consolation.

Police told us tends to go in phases, a few guys move into a neighbourhood, spate of muggings, robberies and are gone at some point.
