(Getty Images) (Newser) – What might have sunk Best Buy's Brian Dunn? That thing that often fells men in power: allegations of an affair with a female employee—and there's a twist. The Minneapolis Star Tribune reports that the former CEO is accused of using company resources to facilitate that relationship. Best Buy offered no comment, and the Star Tribune is light on any supporting details. A source tells the paper that the company is looking into "multiple complaints that Dunn behaved inappropriately with a female subordinate."
