He used a network of associates in England to run a string of sham agencies and photography studios in cities including London, Manchester, Leeds, Bristol, Coventry and Nottingham which was uncovered after a six-year NTS investigation.
The victims were duped into thinking that a model agency was interested in them, with emails telling them they had potential after they responded to a local photographic studio and social media advertising campaign.
They were told they had to buy their portfolio photographs from the studio in order to join an agency and become an agency model.
Some of them used credit deals arranged by the fraudsters or expensive payday loans to make the upfront payment.
In return, the victims got poor quality digital photographs that stood no real chance of landing them professional jobs and most did not get paid modelling work.
Foster bought high-end watches and cars with his share of the proceeds while many victims told NTS investigators they had been left financially and emotionally devastated, and felt humiliated and betrayed.
