The Land Transport Authority is still compiling its report on the two bus fires that occurred last month.
This has been confirmed by LTA CEO Carmine Piantedosi who says the cause of both bus fires is still yet to be determined.
A Pacific Transport bus caught fire along Malaqereqere in Sigatoka and 52 passengers escaped the bus fire unharmed on the 18th last month.
Police had initially said the fire started from the engine.
A Tebara bus also caught fire at the roundabout near the Nausori Health Centre last month.
No one was injured.
