Briton suspected of spying for Russia ‘kept himself to himself’

Neighbours know little of David Smith though Russian flags are visible inside his Potsdam flat

A security guard at the British embassy in Berlin who has been arrested on suspicion of passing state secrets to Russia lived in a two-room flat on a tidy estate in the city of Potsdam.

David Smith was arrested at his home on Tuesday and the contents of his apartment are likely to become a focus of the ongoing inquiry into whether he sold documents to a representative of a Russian intelligence service" in exchange for cash.
