The “targeted” arson attack on Kid Cudi’s Porsche convertible was carried out with a Molotov cocktail fashioned from a malt liquor bottle and silky designer handkerchief, a fire investigator testified at Sean “Diddy” Combs’ bombshell federal trial Wednesday.

Combs' defense claims that a "witness generally cannot testify that in his opinion, a declarant was lying when making a statement"

As per ABC News, in his testimony, Jimenez said that a partial female DNA profile was found on the Molotov cocktail bottle discovered in Kid Cudi's car while investigating. However, he added that he couldn't conclude anything from it.

The testimony ties directly into Cassie’s earlier claims that Diddy lost it when he learned about her and Cudi, allegedly vowing to blow up the Man on the Moon artist’s car. Cudi also testified that when he later confronted Diddy about the explosion during a meeting with Cassie at Soho House in L.A., the music mogul played dumb.

Combs, who is on trial for sex-trafficking, racketeering and transportation to engage in prostitution, sat a few feet away from Kid Cudi — whose real name is Scott Mescudi — as the Grammy-winning rapper recounted alleged threats Combs made when he learned Mescudi was dating Combs' ex-girlfriend Casandra "Cassie" Ventura.

Police and fire investigators who looked into the rapper Kid Cudi’s allegations and a celebrity stylist who said he witnessed several assaults testified Wednesday in the third week of Sean “Diddy” Combs’ federal criminal trial.
