Scottsdale, Ariz. police are looking to speak with Diddy after an upset fan claims that the rap mogul punched him at a pre-Super Bowl party over the weekend. In a video obtained by TMZ, the victim, Steven Donaldson, can be heard yelling at Diddy for showing up to the event late and not performing like he was scheduled to. The video doesn't show an actual altercation between Donaldson and Diddy, but Donaldson does get thrown out of the party by Diddy's security after attempting to confront him. Diddy reportedly left the event before the cops arrived, but Donaldson did end up filing a battery report. We will continue to update this story as details from the incident emerge.
