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.

In an appearance at the US District Court in New York, Mr Combs was charged with sex trafficking, racketeering and transportation to engage in prostitution. In an indictment that was unsealed at the same time, prosecutors alleged that he also engaged in kidnapping, forced labour, bribery and other crimes.
