New Delhi, March 21 (TIWN) The Special Cell of Delhi Police has filed a 1040-page charge sheet in the Rohini Court IED explosion case, a police official said on Monday.

On December 9, last year, a low-intensity blast ripped off inside courtroom number 102 of Rohini court complex at around 10.30 a.m. injuring one person present within the blast radius.

The police had said that accused Bharat Bhushan Kataria, 47, planted the IED at a place where a lawyer was likely to sit inside the courtroom, as he was "highly frustrated due to the protracted legal battles which were causing problems in his career as well as prolonged mental harassment and monetary loss to him and his family".

After the blast, an FIR under section 307 of the Indian Penal Code and section 3 of the Explosive Substance Act was registered at the Special Cell police station and investigation was taken up.

During investigation, after analysis of CCTV footages of more than 150 cameras, verification of more than 1000 vehicles that entered the court premises on the day of incident, interrogation of hundreds of persons including advocates, litigants, police personnel's persons with past criminal history, the police team identified the culprit Bharat Bhushan Kataria behind the incident.
