The tailor is a false lead. But the cycle seller is not. The cycle buyers must have been staying within walking distance of his shop since blast occurred within hours. So inquiries need to be made withn a limited area.
Police had claimed that the only injured person in the blast(a tailor), had visited Jordan and he did not tell police about that when enquired. So where is that angle and answer to it?
Police should also check the STD records to and from Pak if any new numbers are there since the decision to place the bombs in such a manner was a bit hurried with flawed bombs.
