KOCHI: Though the Special Investigation Team probing into the blast at the District Collectorate on July 10 last year have almost zeroed in on the main suspect, the case is nowhere near closing.
The investigators have traced the suspect, believed to be having a direct link with Lashker-e-Taiba, to Oman.
But he could not be extradited as India does not have an extradition treaty with Oman.
A senior police official involved in the investigation said that the chances of bringing him over weigh mostly on the National Investigation Agency, by including him as a suspect in cases of terrorism already being probed.
This could be done as main suspects are linked to all activities.
