Police sources, however, say they are verifying some indications that Yahya, who used to come down from Bangalore once every few months, was in close touch with elements of the banned SIMI who had since gone into other innocuous front outfits.
Kozhikode was a major SIMI base until the ban. That apart, sources say Yahya has been under surveillance and investigation in Bangalore for over a couple of years now, his mobile phone number was found in the pocket of one of the two militants killed in J&K two years ago.
