Unless the investigation comes to a logical end, i can never believe in these rumours. Police in Hyderabad are under pressure to bring up evidence and make some progress on the blasts. They were never able to even pin-point to the accused in the last couple of blasts that happened over a time of a decade (The blast at Saibaba temple at dilsukhnagar and the mecca masjib blast). I am forced into believing that they are coming up with these concocted intermediate 'findings' only to keep the media and the public calm...and trying to avoid facing any wrath.
Catch the culprits, punish them and let us know about it. Only then would hyderabadis be satisfied.
