Diddy is wanted by police after a fan alleged he was punched in the face by the star.
According to TMZ, Steven Donaldson has claimed the 45-year-old star struck him at a Super Bowl party on Saturday night (31.01.15) which the rapper was supposed to host by didn't turn up until 1:15am (01.02.15) and spent most of his time in the VIP area.
In a video obtained by the gossip website, the accuser - who splashed out $100 for the bash - can be heard slamming Diddy and they end up face-to-face before the clip cuts out.
Steven claims the star then went on to strike him and he was thrown out by security while Diddy remained at the party.
According to law enforcement sources, Steven filed a battery report with police at the scene but the US record producer had left by the time they turned up.
Scottsdale Police are now said to be keen to question the 'Shake Ya Tailfeather' hitmaker to get his version of events.
The accuser was said to be annoyed at Diddy because he had forked out $100 to see him at the event but he seldom saw him on-stage at the bash.
In December 2014, it was reported Diddy punched fellow rapper Drake during a brawl over music rights to a song outside a Miami nightclub.
