Sean "Diddy" Combs has found a new passion behind bars, teaching aspiring inmates entrepreneurial skills to use upon their release. Raymond Castillo, a former inmate at Brooklyn's Metropolitan Detention Center with Diddy, 56, spoke to Us Weekly exclusively about the positive change the rapper's "Free Game With Diddy" program brought to the jail. "Everything was smooth after that. Diddy brought unity to the unit, because the unit was really divided," Castillo told Us on Thursday, November 13, adding that "everybody was segregated" until the disgraced mogul started the program.
