Bike thieves, Gumtree, and retrieving one's possessions

Isn't the whole point of having a Brompton to be able to fold it up and take it with you, thereby eliminating the possibility of theft?

pretty much the same reason I gave my girlfriend before she got one.

sound like someone broke in the house and stolen the Brompton? thought even with the folding capacity, some people still lock them up outside their workplace since they can't be bothered dragging the heavy bugger upstair to their desktop.
