NIA started probing an email sent by Indian Mujahideen (IM) which on Thursday, Sep 8 claimed that they were responsible and masterminded the blast outside the court in the national capital.
The Ministry of Home Affairs (MHA) official also informed, "Mail can't be ignored, we will investigate it." Indian Mujahideen is being parented by the Lashkar-e-Toiba (LeT).
Earlier Harkat-ul- Jehadi (HuJI) had claimed the responsibility of the blast. It has also been reported that HuJI had sent an email to a media house citing that this blast in the High Court was in retaliation to the death sentence pronounced on Afzal Guru, who has been convicted in the Parliament Attack case.
