The court took the decision due to lack of evidence provided by the NIA against the accused.
The blast which took place on May 18, 2007 at the Mecca Masjid in Hyderabad during Friday prayers had killed eight people and left 58 injured. It was allegedly carried out by a group of right-wing terrorists.
However, only five of them namely Devendra Gupta, Lokesh Sharma, Swami Aseemanand, Bharat Mohanlal Rateshwar and Rajendra Chowdhary were arrested and faced trial in the case.
Two other accused- Sandeep V Dange and Ramchandra Kalsangra- are absconding, while one of the accused, Sunil Joshi was allegedly murdered while the case was being investigated.
The remaining two accused are also untraceable.(ANI)
