Since federal agents raided two of Sean Combs’s homes in Los Angeles and the Miami area this week, the investigation into the hip-hop mogul has become the subject of intense public interest and speculation.

The raids were conducted by Homeland Security Investigations, which has said very little about the focus of its inquiry. No criminal charges have been filed against Mr. Combs in relation to the case.

But the footage of federal officers brandishing weapons while entering Mr. Combs’s sprawling Los Angeles mansion, where they confiscated computers and other devices, has raised questions about the nature of the investigation and how it might relate to a series of civil sexual assault lawsuits filed against Mr. Combs in recent months.

Mr. Combs — a high-profile music producer and artist for decades who has been lauded as one of the architects of hip-hop’s commercial rise — has vehemently denied all the accusations, and his lawyer called the raids a “witch hunt based on meritless accusations made in civil lawsuits.”

As details about the federal investigation gradually emerge, here is what we know about Mr. Combs’s legal troubles.
