Bangalore/New Delhi, Oct 28 (ANI): The BJP on Monday demanded a CBI investigation on the recent bomb blasts in Bihar. Explosions at the election rally of BJP’s prime ministerial candidate Narendra Modi killed 6 people and wounded over 80 in Patna on Sunday. BJP leader Giriraj Singh said CBI should investigate the matter and find out the hidden facts. Even though the BJP has alleged that the central and state governments are responsible for the incidents, Congress General Secretary Digvijay Singh passed the buck to the Bihar state government alone.
