Five people were found dead in Nadi on Monday with post-mortem examination results showing all five died as a result of ingesting a toxic substance; however, police have not yet revealed what that substance is.
The bodies of 63-year-old carpenter Nirmal Kumar, his 54-year-old wife Usha Devi, their 34-year-old daughter, Nileshni Kajal and her two daughters aged Sana, 11, and Samara, 8 were found.
Samaira Kumar, 1, was also found crying by the roadside close to where the bodies were found.
Government-owned FBC News reported a man from New Zealand was questioned but no charges have yet been laid.
Police appealed for the New Zealand man to be held for more than 48 hours in a bid to continue their line of questioning, but the court dismissed the application.
It is understood that a second person, related to the man, has also been questioned, according to FBC News.
In a statement to the Fijian Times, police spokesperson Ana Naisoro said more tests would be conducted by the Fiji Police Chemistry Scientific Lab in Nasova following post-mortems on the five victims.
Investigations are ongoing.
