I did do a bit of nicking as a kid but was generally around Richmond estate close to brook school and scrumping in Richmond Park.
I have just lost touch with all the people who used to live in that area, eg Garry and Sharon Hardy, Pete and co of the Rippon family, a woman down the street who introduced me to sex but can't remember her name, Anne somebody I think. Then there was Martin Dixon who I believe became one of the plod mentioned above.
Maybe someone knows them or others from the area at that time.
