New Delhi, Nov. 27 -- The National Investigation Agency (NIA) has arrested a 32-year-old resident of Faridabad, Haryana, for allegedly providing shelter and logistical support to Dr Umar-un-Nabi, the alleged suicide bomber behind the November 10 Red Fort blast, officials said on Wednesday. The accused, Mohammad Shoaib of Dhauj village, is the seventh person to be nabbed in the terror probe, the officials added. According to investigators, Shoaib allegedly played a crucial role in the days leading up to the attack, harbouring Umar and assisting him with "critical logistical arrangements", including movement, concealment and safe accommodation. "The arrest was made on Tuesday after NIA teams, acting on fresh leads, picked up Shoaib during coordinated operations in the National Capital Region. We have registered a case against him," said a senior NIA officer, requesting not to be named. Shoaib's arrest has helped the agency fill in an important gap in the timelines of Umar's movement before the explosives-laden vehicle blew up near the Red Fort, said the officer, adding that evidence pointed to Shoaib playing a knowing role in providing safe passage and support. "His custody will help us map out the wider support network that enabled the bomber," the officer said. HT earlier reported that Shoaib, a nursing staffer at Al-Falah University, had arranged Umar's accommodation for 10 days before the blast at his sister-in-law's room in Hidayat Colony in Haryana's Nuh. Shoaib was also the allegedly driver of a white i20 in which Umar escaped the Al-Falah campus on October 30 after investigators apprehended Dr Muzammil Shakeel Ganaie, one of the key conspirators in a "white-collar" terror module. That i20 was later used in the blast. Another NIA officer said that the conspiracy is "multi-layered" and that identifying every link remains its top priority....
