DUESSELDORF (Reuters) - Hugo Boss' second-biggest shareholder, British sports and fashion retailer Frasers, has filed a request to acquire more shares in the German company, according to a filing with the German competition authority seen by Reuters on Friday.

A spokesperson for the Bundeskartellamt authority did not provide any information regarding the amount of shares that Frasers intends to buy.

The watchdog, which examines the impact of mergers on the German market, now has one month to assess the plans.

Frasers was not immediately available for comment.

Earlier in August, Hugo Boss said it received a regulatory filing stating that Frasers exceeded a 15% threshold with its stake.
