A man has been arrested after allegedly illegally disposing of 17,000 tonnes of asbestos but enforcement agencies have no idea where the potentially deadly waste has been dumped.
NSW Police late last week arrested a 48-year-old waste disposal company director at Sydney Airport as he tried to flee the country.
They allege his company removed approximately 600 truckloads of asbestos-contaminated building waste from the Green Square redevelopment from mid-2016.
The subcontractor for the City of Sydney project initially provided documents showing it had correctly disposed of the asbestos but anomalies were uncovered after almost a year of work, NSW Police say.
Specialist police squads on Thursday raided four properties connected to the director and his business including a rural property at Kemps Creek in Sydney's west.

AAP understands some suspected waste was found at the property which will be subjected to testing.
However, it accounts for only a fraction of the 17,000 tonnes of potentially cancer-causing waste, AAP believes.
Police and the NSW Environment Protection Authority are unable to say if people have been exposed to any waste and are urging anyone with information to come forward.
The man will face court on Friday charged with multiple serious fraud offences.
