Law enforcement agencies on Monday arrested a college student in Rawalpindi on suspicions of his involvement in the Ayub Park blast and shifted him to an unidentified location for investigation, Daily Times has learnt. Law enforcement agencies’ officials were tipped off about a male suspect living in a deserted house near Bhosa Mandi, in the limits of Gunj Mandi Police Station, sources said. Agency officials raided the house and arrested 25-year-old Mohammad Nadeem, a college student, on suspicions of his links with Al Qaeda, they said. Sources said police searched Nadeem’s family house in Mara Jafer, a slum in the limits of Golra Police Station, and seized some “important documents”, without mentioning their content. Law enforcers have termed the arrest a significant headway in the probe into the Ayub Park blast and the recovery of four rockets in Islamabad. However, Syed Murvat Ali Shah, the Rawalpindi police additional inspector general, also a member of the joint investigation team, denied that the police have arrested the student. He claimed that investigators are getting closer to the culprits and will soon arrest them.
