New Delhi, Sep 26 : A number of PFI members were earlier associated with banned organisations like the Students Islamic Movement of India and the Indian Mujahideen, National Investigation Agency (NIA) sources claim. PFI leader Abdul Rehman reportedly used to be national Secretary of the SIMI, they said, adding that Abdul Sattar, the state Secretary in PFI, was also associated with SIMI in similar capacity. Sources also claimed that PFI leaders had allegedly been hatching conspiracy with Pakistan-based handlers to carry out anti-national activities. They were also getting instruction from Gulf and Middle Eastern countries, the sources added. According to sources, PFI member Mohammed Sakib allegedly sent money to the PFI through hawala channels from Pakistan and was allegedly in touch with Pakistan-based handlers, who wanted to reach out to Pakistani prisoners lodged in different jails. Then S. Ismail, a friend of Sakib was allegedly working for people who were supporting ISIS activities in India, the sources said. They also claimed that lot of hawala money was pumped into India for anti-national activities and linked the barbaric attack on Kerala professor T.J.
