Even as three years have passed since the pipe bomb explosion at the Kakkanad Collectorate on July 10, 2009, the police are yet to trace the people involved in the case.
A Special Investigation Team (SIT) was formed and as many as 50 persons, mainly those involved in terror cases, were quizzed in this regard.
“From the forensic test it was evident that glyceryl trinitrate, also known as nitroglycerin, was used to make the bomb that exploded in the fifth floor of the collectorate.
The same chemical was used for making bombs in several other blasts carried out by terror groups in many South Indian cities.
So, we suspected the terror groups which was involved in the burglary taken place in Kizhakkambalam.
But even after quizzing the persons involved in it, including Thadiyantavide Nazir, no solid evidence was extracted.
We had prepared a list of persons and quizzed them, but they did not reveal anything,” an SIT official told Express.
However, another official said that they will also hunt for other suspected groups other than terror outfits.
“We are examining the possibility of the involvement of other groups such as Maoists in the case,” said the official.
