Fiji's police commissioner is under formal investigation after accusations were levelled against him that he obstructed police.
On Sunday, Major General Ben Groenewald released a statement saying a South African diplomat had been treated at hospital and released without charge after being involved in a fatal car accident.
He said the diplomat had full immunity from the Fijian authorities and was protected by the Vienna Convention.
Yesterday, the Assistant Commissioner of Police, Henry Brown, confirmed a report was filed with police.
Mr Brown says investigations are continuing and he will release more details at a later date.
Ben Groenewald had informed the police director of traffic after the incident that he should be released according to the convention.
The convention also allows for a country to waive the right to immunity in specific cases.
