Some of the similarities in the cases brought against Sean “Diddy” Combs this week and Robert Sylvester Kelly several years ago are evident at a glance: Both are world famous, powerful and influential musicians who were accused of sex crimes by federal prosecutors in New York City.

Jailers put accused sex trafficker Sean "Diddy" Combs on a "procedural" suicide watch, as the music mogul awaits trial on three felony counts tied to more than a decade of alleged abuse. NBC News' Chloe Melas reports on the conditions and reputation of the Metropolitan Detention Center where Combs is detained.

Combs, who is facing charges of sex trafficking and racketeering, is currently being held in Brooklyn's Metropolitan Detention Center on suicide watch, after his arrest in Manhattan Monday and subsequent bail denial, according to People.
