The FBI raided all p diddy's properties at the same time the other week. Apparently he paid tens of thousands for this footage from the hotel. Sounds like they found it in the raid, along with a ton of other secret recordings of his so-called "freak offs" (orgies) which he used to blackmail people.
He's also alleged to have abused Usher when he was a teenager, and then Justin Bieber, after Usher introduced them. Quite a few people in the rap industry have come forward with stories like this.
