High street footwear chain Office has refused to be drawn on reports that it is subject to takeover bids.

A number of private equity firms are lining up a bid for the retailer, according to UK media reports.

"We have no comment at this time," an Office spokesperson told just-style.

Among the investors said to be interested are PAI Partners, Silverfleet Capital and Blackstone, according to The Independent newspaper.

In June, Office owner Sir Tom Hunter appointed a team of advisers to explore options for the shoe chain, including a possible sale. Hunter's investment vehicle West Coast Capital appointed Hawkpoint in the UK and boutique investment firm Financo in the US to handle the deal.

West Coast Capital bought the 124-outlet chain in 2003, and is thought to be demanding a potential price tag of GBP200m (US$304m).
