The National Investigation Agency on Wednesday said that it has still not received any response from Pakistan on Supplementary Letters Rogatory sent to the neighbouring nation it in connection with the probe in the terrorist attack on the Pathankot air force base.

According to sources, the NIA is trying to collect more information like Jaish-e-Mohammad as a terrorist organisation and its role in the attack.

Sources also said there was use of similar wireless system in terror attacks carried out at Kathua, Samba and Pathankot.

Every target selection and modus operandi was same, so we are not investigating all these cases separately, said NIA sources.

The NIA sources also said that the agency is not denying from the fact that Dina Nagar attack was not handiwork of the JeM.

It is reported that the JeM is allegedly planning to replicate the January 2 terror strike and has activated sleeper cells to carry out recess in cities across north India to set ground for the same.

As per reports, the militant group is being aided by the Inter-Services Intelligence and is also receiving help from Indian Mujahideen to plan fresh attacks.

The Interpol had earlier issued a fresh Red Corner notice against JeM chief Maulana Masood Azhar and his brother Abdul Rauf for their alleged involvement in the Pathankot attack.

According to NIA sources, JeM suspect Shahid Latif is the main handler in the Pathankot attack and that his location at the moment should probably be in Pakistan.

Latif was first arrested in 1994, convicted in 1995 and his jail term was over in 2010. After that he deported to Pakistan through the Atari Border.

Sources added that besides a notice on Masood and Rauf, the Interpol is also in the process of issuing a Red Corner notice against Latif and JeM suspect Shahid Latif.

Masood Azhar, his brother Abdul Rauf, Jan and Latif are being touted as the main culprits into the deadly attack on the Indian Air Force base.
