There has been no progress in the search of the missing Russian couple from their farm in Mulomulo in the Nausori Highlands Road in Nadi.
They have been reported missing since the 16th of this month.
Police Chief of Intelligence and Investigations, ACP Luke Navela said they are requesting people living around or travelling through Natadola Beach to inform them of more body parts washing ashore.
ACP Navela said they discovered another set of human body parts on Sunday and the remains are at the Nadi Hospital awaiting necessary forensic tests.
INTERPOL has been called to assist in the discovery of the body parts and the investigation into the missing Russian couple at Natadola Beach.
He said at this point they cannot positively confirm if the two cases are linked.
A security guard had discovered the first set of body parts at Natadola Beach on Friday.
