Papua New Guinea Police have placed three charges against an Australian reportedly working under the Enchanced Cooperation Programme
John Jones of Brisbane was charged with failing to comply with a police direction, provoking a breach of peace, and drunk driving with undue care earlier this month.
Mr Jones appeared briefly before in the Waigani Comitial Court on Friday before his case was adjourned until October 19.
Central Police Commander Tony Wagambie says doesn't know if the Australian, who is an employee of a company engaged under the ECP, is elligible for immunity or not.
But he says police are dealing with Mr Jones just like any member of the public.
"I don't know whether he's part of the ECP or he's just a sub-contractor. We know he's a sub-contractor but whether he's qualified for immunity, I don't know. Like I said, I don't know what's this media hype about."
Tony Wagambie says investigations have also been launched into allegations that Mr Jones was beaten up by police at the site.
