A fire which killed a Rotorua teenager started near mechanical equipment and police say there is nothing to support claims a molotov cocktail was used.
Rotorua teenager Mihinui Tamiana died during the fire at an industrial building on Riri St on Sunday morning.
A few hours earlier police were called to the building to shut down a party.
A friend of Mihinui said she believed a molotov cocktail was thrown into the building and started the fire but Detective Senior Sergeant Zane Smith said there was nothing to support those claims.
"We fully appreciate that the family of the teenager who died and the wider community want to know what caused this fire. It has been a tragic loss of life and it is vital that we are thorough in our investigation," he said.
