FEDERAL police have raided several companies associated with Perth Glory owner and businessman Tony Sage.
It is understood the Australian Federal Police spent several hours in the soccer club's Leederville building as well as at the office of the mining company Cape Lambert Resources, which Mr Sage chairs.
A federal police spokeswoman said she could not comment on a continuing investigation but did confirm several commercial and residential premises were raided in Perth and Sydney on Wednesday.
''The AFP can confirm that today a number of search warrants were executed on commercial and residential premises in Perth and Sydney,'' she said.
The searches were part of a continuing AFP investigation in partnership with Commonwealth agencies, including the Australian Crime Commission, the Australian Taxation Office and the Australian Securities and Investments Commission, she said.
''The investigation is ongoing, therefore it is not appropriate to make any further comment at this point in time,'' she said.
Cape Lambert Resources and the Perth Glory both said on Wednesday they would not comment on the matter.
Mr Sage could not be contacted.
Cape Lambert was hit this year with a $95 million tax bill, including costs, after an audit of the company's 2011 half-year results.
It is unclear whether the two matters are related
The tax discrepancy involved the sale of the Cape Lambert Iron Ore project in 2008, and the acquisition of the CopperCo Group of assets in June 2009.
Last month Cape Lambert said it would make a $33 million ''provisional payment'' to the ATO, until a final decision on the tax matter was made.
At the time, Mr Sage said he was confident negotiations with the ATO would result in a favourable outcome for Cape Lambert, although he cautioned that a final result could take as much as three years.
