Scott Mescudi said his Porsche was set on fire with a molotov cocktail on day nine of Combs’s trial in New York

Scott Mescudi, known as the rapper Kid Cudi, testified on Thursday in the federal racketeering conspiracy and sex-trafficking trial of music mogul Sean “Diddy” Combs, alleging that Combs broke into his home in 2011 after discovering that he was dating Combs’s on-again, off-again girlfriend, the singer Casandra “Cassie” Ventura, and told the court how a molotov cocktail was thrown at his car a few weeks later.

Combs, 55, faces charges of sex trafficking, racketeering conspiracy and transportation to engage in prostitution. He was arrested in September, and has pleaded not guilty to all charges.
