SRINAGAR: The 32-year-old Kashmiri man arrested along with his wife in Delhi last Sunday on suspicion of working for Islamic State is an IT professional who went to two of Srinagar's top Christian missionary schools, played competitive cricket at various levels and ran a software startup before unrest in the Valley cut short his entrepreneurial journey and forced him to take up a job, his family said on Wednesday.Sehrish Sami, the younger sister of Jahanzaib Sami Wani, said her brother did not have any adverse police record or history of radical behaviour. "My brother and sister-in-law read the Quran and other religious books, like many Muslims do. How are those 'incriminating' material, as claimed by Delhi Police? Is reading religious literature a crime?" she said.Till late on Wednesday, J&K Police apparently hadn't found anything on Jahanzaib or his wife Hina Bashir suggesting their involvement in illegal activity in the Valley. "We are gathering details as of now," Srinagar SSP Haseeb Mughal said.An alumnus of Burn Hall and Tyndale Biscoe schools, Jahanzaib is the son of businessman and councillor Sami Wani. The family resides in the upmarket Shivpora locality of Srinagar, adjacent to the military headquarters in J&K.According to Sehrish, her brother wouldn't have left home late last year had the internet shutdown since August 5 not made it impossible for him to work out of the Valley as a project manager of a UK-based IT company. "The last time we spoke, he and my sister-in-law were all set to return home as internet services have just been restored in Kashmir ," she said.Jahanzaib and Hina, an MBA in finance and marketing, got married on October 6 and moved into a rented home in Delhi's Okhla neighbourhood on October 26. His employer arranged the accommodation, Sehrish said.Muzaffar Shah, a neighbour of the family in Shivpora, said there was nothing in Jahanzaib's behaviour to suspect he had been radicalised and roped in by a terror outfit like IS.Back in 2016, when Kashmir was in the throes of unrest over Hizbul Mujahideen terrorist Burhan Wani 's death in an encounter with security forces, Jahanzaib was too busy trying to keep his startup WalurSol afloat, his sister said.“My brother worked in Bengaluru for some time after completing his BTech there. He then returned home to launch WalurSol, which shut down in the wake of the violence in 2016,” Sehrish said. “He again took up a job in Pune, although his heart was always here despite our father wanting him to settle outside Kashmir."Jahanzaib's father Sami and father-in-law Bashir Ahmad Beig are currently in Delhi trying to arrange "legal remedies" for their wards, family sources said.On Sunday, Delhi Police’s special cell announced the arrest of a Kashmiri couple living in a rented flat at Jamia Nagar in Okhla for their alleged links with the Khorasan module of IS. Claiming to have found "objectionable material" in their possession, the police accused the couple of also inciting protests against CAA.Sehrish said she came to know about her brother and sister-in-law's arrest from their landlord. "I then spoke to one of our cousins in Delhi and asked him to find out what had happened."Jahanzaib's mother, a former schoolteacher, is still in shock. “She can't believe her son and daughter-in-law have been picked up on frivolous charges. Our mother has always been proud of Jahanzaib's calibre, and for him to be accused of being radical and an IS operative is beyond imagination," Sehrish said.
