This has been claimed by one of the eye-witnesses, Mahender who had come to the High Court for a hearing. The explosive device was suspected to have been kept in a briefcase outside the High Court.
"When I was standing in the line along with my friend, one person came in a white shirt with a briefcase in his hand and within seconds there was a blast. I could not see anything," Mahender said.
He said he sat on the floor after the blast took place only to see the person who was accompanying him was injured. "I asked him to go out and a policeman came and helped us immediately. Police reached the spot within minutes and helped people," he said.
On other hand, terror group Harkat-ul-Jihad-al-Islami (HuJI) has claimed responsibility for the blast. So, these clues and hints lead us to several such probable questions about the suspect behind the blast. It is also being suspected that the man in "white shirt, carrying a briefcase" might be a member of HUJI? The nation is awaiting these crucial answers over the medium-intensity blast that rocked the capital city, leaving many casualties.
