A gangland phone firm linked to the death of Dutch underworld figure Martin Kok offered hackers £1million if they could crack their security.
Glasgow-based MPC Secure Communications Ltd is alleged to have close links to suspected crime kingpins James and Barry Gillespie.
It is thought to have raked in more than £6million from selling encrypted handsets to organised crime gangs around the globe before it dissolved after just 18 months in business.
