THIRUVANANTHAPURAM: Scientific evidence will be decisive against Shahrukh in the train arson case. Shahrukh's books, a bottle filled with kerosene and a t-shirt were recovered from the bag left by him near the railway track at Elathur. The book had Shahrukh's address. The father has confirmed that Shahrukh wears this T-shirt at home. Forensic experts have found fur and hair from it. If it is proved to be Shahrukh's then it will be a strong proof.

Fingerprints were also found from the petrol bottle. This will also be crucial. Shahrukh's arrest was made public after showing the picture to the eyewitnesses on the train. The fact that there are eyewitnesses to him pouring kerosene and setting fire will strengthen the case. Six of his mobile numbers were monitored by the Intelligence Bureau. But to mislead the investigation, a mobile phone without a SIM card was left in a bag by the track. But finding the number that Shah Rukh used regularly and being able to locate it when it was switched on turned out to be crucial.
