Papua New Guinea's chief justice Salamo Injia has been charged with sedition following a two-hour negotiation with police, Australia's media reported on Friday.

Deputy Prime Minister of Papua New Guinea (PNG) Beldan Namah and a group of police officers stormed into Salamo Injia's courtroom on Thursday afternoon, trying to arrest him while he was hearing a Supreme Court case, according to Australian Broadcasting Corporation (ABC) reports.

However, the PNG chief justice ran away to a separate room in the chambers and locked himself in.

After a two-hour negotiation, PNG police escorted him to a courtroom for a formal interview.

He was then charged with sedition and released on bail, the ABC reported.

Australian Foreign Minister Bob Carr has contacted the PNG government to express the Australian government's concerns about the latest developments in PNG.

"It's not good for the image that Papua New Guinea sends to the world, to its diplomatic partners or to its investors, to see action of this type," Carr told ABC Radio on Friday.

"Action around the chief justice should cease and all sides should act with restraint."
