Workers have picketed the Bentley office of a State-backed computer game company which is being investigated by the Fair Work Ombudsman and pursued by the Australian Taxation Office.
US-founded Interzone agreed in 2007 to establish a Perth development studio after accepting a State Government offer of $500,000 in financial support as part of a bid to develop a games industry.
The company was expected to create 300 local jobs.
However, Interzone's remaining 15 staff are picketing its studio in the Bentley Technology Park, claiming they are owed back pay and superannuation.
A spokesman for the Fair Work Ombudsman yesterday confirmed it was investigating complaints against Interzone.
It would not disclose the nature of the claims, but one worker, Felix Wai said the company owed employees more than $500,000 in "wages and superannuation which they haven't been paying for about 18 months, maybe more".
Australian Securities and Investments Commission records show Interzone has just one director, its US-based co-founder Marty Brickey, after the resignation of two fellow directors early last month.
Repeated attempts by _The West Australian _to contact Interzone management were unsuccessful.
Sources also confirmed that the ATO last month filed a statutory demand against Interzone seeking the payment of more than $1 million.
Police were called to the Interzone office on Wednesday when a former company official tried to remove computer equipment.
"It contains all the intellectual property we have been working on for the last 18 months, IP which they haven't paid for yet," Mr Wai said.
Mr Brickey set up Interzone at Bentley with Perth computer game designer, Robert Spencer.
However, Mr Spencer left the group in late-2007 after a difference of opinion over strategy.
"It was my baby and this is very saddening," he said yesterday.
