Best Buy chief resigns amid probe
Best Buy boss Brian Dunn has resigned abruptly after the troubled consumer electronics chain launched an internal investigation into his "personal conduct".
Minneapolis-based Best Buy said that it was conducting the probe after initially only saying the departure was a "mutual decision". But the chain would not give any specifics on the circumstances surrounding the investigation of Mr Dunn, a 28-year Best Buy veteran who had been chief executive since 2009.
