Sean "Diddy" Combs was ordered held without bail Tuesday after he was charged with sex trafficking, racketeering conspiracy and transportation to engage in prostitution. Combs pleaded not guilty to the charges in federal court in New York City. U.S. Magistrate Judge Robyn Tarnofsky ordered Combs held after hearing from prosecutors and Combs' legal team late Tuesday afternoon. Marc Agnifilo, an attorney for Combs, appealed the decision Wednesday and lost. Prosecutors sought detention for Combs, arguing that he "poses an ongoing and significant danger to the community, has repeatedly engaged in obstructive conduct, and presents a serious risk of flight," while his lawyers asked that he be released on bond.
