Virgin Australia flight crew allegedly assaulted, robbed in Fiji, police ...

Police in Fiji are investigating the alleged assault of Virgin Australia crew members during a night out on New Year's Eve in the tourist town of Nadi.  

Police said the incident involving two crew members, a man and a woman, occurred outside the Bar One nightclub on Tuesday night.

Assistant Police Commissioner Mesake Waqa said the man was robbed and the woman was sexually assaulted.

The man was taken to hospital and treated for facial injuries.

The pair remain in Fiji at a hotel in Nadi.

A Virgin spokesperson said the airline was aware of the incident and "our focus is on the wellbeing of our team members affected".

What we know about the Fiji alcohol poisoning

Health authorities are investigating following the hospitalisation of six people who became critically ill after drinking cocktails in tropical Fiji. 

A Department of Foreign Affairs and Trade spokesperson said they were aware of the incident but due to privacy obligations they couldn't comment further.

Acting Police Commissioner Juki Chew Fong said the suspects were locals and no arrests had been made yet.

He told local media that police were committed to providing visitors a safe environment this festive season.

It is more bad news for Fiji's tourism industry after seven people, including four Australian tourists, were hospitalised after drinking the same cocktails at a resort last month.

The cause of the poisoning remains a mystery.

Fiji's authorities said tests on drinks at the Warwick Resort found no traces of methanol but the results of the samples taken from the patients poisoned have not been released.
