What's next in the federal investigation into Sean 'Diddy' Combs and his alleged co-conspirators

Sean "Diddy" Combs, who was arrested this week on charges of racketeering conspiracy and sex trafficking, pleaded not guilty Tuesday and was ordered to remain in custody until his federal trial in New York. CNN spoke to several legal experts to try to understand what lies ahead for Combs and for those in his orbit.

Sean "Diddy" Combs, who was arrested this week on charges of racketeering conspiracy and sex trafficking, pleaded not guilty Tuesday and was ordered to remain in custody until his federal trial in New York.

So what comes next for the 54-year-old music mogul? And what about the unnamed employees and associates accused of conspiring with him?

Damian Williams, the US attorney for the Southern District of New York who brought the indictment, was vague when asked whether Diddy or others could face more charges.

"I can't take anything off the table. Anything is possible," he said. "Our investigation is very active and ongoing, and I think a lot of you who cover this office know that when we say such things, that developments are certainly foreseeable, but I cannot predict them sitting here today."

Multiple witnesses who have worked for Combs have been meeting with prosecutors, a source familiar with the federal investigation told CNN. At least one male sex worker is expected to testify in front of the grand jury in coming days, according to the source, who added the witnesses' allegations go beyond the details in this week's indictment.

Prosecutors have previously said they have interviewed over 50 victims and witnesses in the case.

CNN spoke to several legal experts to try to understand what lies ahead for Combs and for those in his orbit. The experts do not expect a plea deal for the music mogul, noting the accusations against him could expand further.
