A bankrupt Hell Pizza franchisee has gone to police after a mass of emails he had sent and received were posted online.
Matt Blomfield says the information posted online by blogger Cameron Slater was taken from his office during a burglary in 2010.
Sergeant Grant Hand, of the North Shore police, confirmed a complaint had been received and was under investigation.
The security breach comes a year after Mr Blomfield's computers were seized by the Serious Fraud Office.
At the time, he said he was "squeaky clean".
