Faridabad, Nov. 19 -- Dr Umar un-Nabi spent close to three years in Faridabad where he worked at Al-Falah Medical College, and when investigators cracked down on his terror module, he fled for nine days to Nuh. In both places, the alleged suicide bomber behind the deadly blast near Red Fort left fear, panic and confusion in his wake. In Nuh's Hidayat Colony, where Umar stayed until the eve of the November 10 blast, families are now fleeing their homes, unable to withstand the relentless presence of police, the cloud of suspicion and public scrutiny. Meanwhile in Faridabad, students at Al-Falah said they are uncertain about their future. Umar hid in a 10x12 ft room in a house at Hidayat Colony in Nuh for nearly 10 days before the blast. At least 10 families have temporarily abandoned their homes in the locality, fleeing what they describe as constant police visits and suffocating fear since investigators identified the house. The room where Umar stayed belongs to Afsana, who is currently in custody as part of the probe. The accommodation, according to police, was arranged by Shoaib - a nursing staffer at Al-Falah University, and Afsana's brother-in-law, who has also been apprehended. Since last week, teams from the Delhi Police Special Cell, NIA and Haryana Police have been visiting the lane round-the-clock. For residents, the disruption became unbearable. "There were police teams coming every few hours, asking us things again and again. We got scared. Most residents have fled. The neighbour next to us left yesterday morning," said 21-year-old Mahesh Valmiki, who locked his home and left with his family and came to pick his two-wheeler that was parked outside the gate on Tuesday. The street outside was mostly deserted when HT visited on Tuesday - shutters were down, slippers left at doorsteps, as if families fled mid-routine. Only a few shops at the far end of the street continued to operate.. At Al-Falah Medical College, classes are technically still being held, but the campus is now practically deserted. The tension began building after the arrest of three doctors linked to the alleged "white-collar" terror module - Dr Muzzammil Shakeel Ganaie and Dr Shaheen Shahid. The chairman of the Al-Falah group was arrested by the Enforcement Directorate on Tuesday on money laundering charges. A third-year Kashmiri MBBS student, who did not want to be named, said he had no idea what the institute's future holds. "Every day another teacher stops coming. We came here to study medicine, not fear raids and arrests. We don't know what's happening inside our own campus," he said. A second-year student from Srinagar said the uncertainty is so overwhelming that many students are considering whether to continue at all. "If the college's affiliation gets cancelled, what happens to us? How do we explain to future employers that our campus turned into a terror investigation site?" Two senior professors from Uttar Pradesh, who still report for duty, said they feel abandoned by the administration. Just outside the university gate, at least a dozen commercial establishments around the university have seen their daily business disappear. Mohammad Abeer, who runs the only restaurant near the university entrance, said his business has evaporated overnight. At Noor Pharmacy beside the main entrance, owner Taslim Khan said patients have stopped coming entirely....
