Sean 'Diddy' Combs seeks release as he awaits trial

Sean "Diddy" Combs is appealing a judge's decision to keep him in jail while he awaits trial on sex trafficking charges.

The hip-hop mogul's lawyers have filed a notice of appeal in the 2nd US Circuit Court of Appeals after previously saying they would ask the court to overturn Judge Andrew L Carter's ruling and release him.

Combs, 54, has been locked up at the Metropolitan Detention Centre in Brooklyn since pleaded not guilty on September 17 to charges that he used his "power and prestige" to induce female victims into drugged-up, elaborately produced sexual performances with male sex workers in events dubbed "Freak Offs".

Carter rejected a defence proposal that would have allowed the I'll Be Missing You singer to be placed under house arrest at his Florida mansion with GPS monitoring and strict limits on visitors.

The judge said the plan, which included a $US50 million ($A72 million) bail offer, was "insufficient" to ensure the safety of the community and the integrity of Combs' case.

Carter said "no condition or set of conditions" for Combs' release could guard against the risk of him threatening or harming witnesses.

Combs' lawyer, Marc Agnifilo, had suggested moving him from the Brooklyn jail, which has been plagued by rampant violence and horrific conditions, to one in Essex County, New Jersey. He later abandoned that idea.

Combs is due back in court for a status conference on October 9.
