Sean Combs is being investigated by Los Angeles police for allegedly attacking a man at an Oscars party. GERARD RECHNITZER claims the rap mogul punched him in the jaw after the 27-year-old realtor objected to Diddy's attempts to woo his fiancee at a Roosevelt Hotel party on Sunday night (25FEB07). According to Rechnitzer watched as Diddy attempted to court his girlfriend and invite her to a private party as he returned from a toilet break. When Rechnitzer stepped in to ask his fiancee to leave with him, Combs allegedly lashed out - and then fled the scene with his entourage. Rechnitzer called the police and filed a report.
