New Delhi: The Gujarat Forensic Science Laboratory, which went into the Godhra train carnage, has found that the fire was caused by inflammable material inside the compartment.

"By taking into consideration the fact that no affect of the fire was found on the bottom side of the coach and also the burning pattern, a conclusion can be drawn that no inflammable fluid had been thrown inside from outside the coach," the four-page report of the Ahmedabad Laboratory said.

The report read out by Railway Minister Laloo Prasad during the course of his reply to Railway budget in Lok Sabha said there also appears to be no possibility that any inflammable liquid was thrown to the door of the bogie leading to the fire that killed 59 persons on February 27, 2002.

Going by the burning pattern inside the coach, its degree and depth, the fire appears to have spread inside the coach very rapidly from Eastern side to Western side, the report said.

"Further, it appears the intensity and proportion of the burning of objects inside the coach was very high, up to around 80 per cent part of the east to west side whereas in the 20 per cent part, the intensity of burning was less.

"By observing the flames of the windows of the coach, it appears that all the windows of the coach were closed during the time of the fire," the report said.

"No sign was observed of the use of any corrosive fluid like acid in the said fire," it said.
