New Delhi: The Delhi Police on Saturday found a switch which is believed to have been used to trigger off the blast at the Delhi High Court, reports say.
Earlier in the day, the Delhi Police had asked for the CCTV footage from over 700 hotels and guest houses for investigation.
Home Minister P Chidambaram on Friday said that there are promising, but no conclusive leads in the Delhi High Court blast case.
So far, four emails claiming responsibility for the Delhi HC blast have been received leaving investigators confounded.
Investigative agencies have detained two people from Rajasthan’s Alwar district on suspicion of their involvement in the terror attack.
Sources said on Saturday that the two have been detained as they resemble the two main suspects whose sketches were released by the Delhi Police.
The duo was held as they were looking for a hotel at Kishangarh Bas in Alwar. The two hail from Anantnag district of Jammu and Kashmir.
Meanwhile, the National Investigative Agency (NIA) probing the case has detained four more people in Kishtwar region of Jammu and Kashmir and is questioning them about the terror email sent on the day of the blast from a cyber cafe in Kishtwar.
