Sean Combs under suicide watch by jailers as he awaits sex trafficking trial

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, a source said.

Combs has been in federal custody in New York City since Monday night and guards at the Metropolitan Detention Center are closely monitoring him in case the defendant attempts to harm himself, a source familiar with the situation told NBC News.

The source described this suicide watch as “procedural with high profile clients."

Combs “remains strong and focused on his defense,” the source added.

A judge on Wednesday denied Combs' appeal for bail, but his defense lawyers are considering additional court action in hopes of freeing their client before trial.

Combs, 54, faces a three-count felony indictment, accusing him of racketeering, sex trafficking and transportation to engage in prostitution in acts that date as far back as 2008.
