More than six hundred Delhi Police personnel assisted by sniffer dogs searched the Jawaharlal Nehru University or JNU campus today to search for clues that could help them trace MSc student Najeeb Ahmed, who has been missing for over two months now. The Delhi Police began its search around 11am under the supervision of DCP (Crime Branch) G Ram Gopal Naik. A team visited Mahi-Mandvi hostel where Najeeb stayed and took help of sniffer dogs who smelled Najeeb's clothes. The sniffer dogs failed to make any headway and stopped after circling around the hostel.
