"He has been arrested under relevant sections of the Foreigner's Act,a police said. Qusay, according to Inspector General of Police Sunil Garg, was picked up from the casino and was being questioned for several hours, about his illegal stay in Goa. "Our police team picked him up from an offshore casino last night after receiving information that he was overstaying in India after expiry of his visa. We have detained him and he is being questioned by police and agencies," Garg had said earlier on Tuesday. Qusay is the second Syrian national who has been arrested for overstaying in Goa, where the police are on high-alert for the last two weeks, after a post card with the letters ISIS, was received by the State Secretariat, which threatened Defence Minister Manohar Parrikar and Prime Minister Narendra Modi with dire consequences because of their alleged anti-beef policies. Less than a week ago, yet another Syrian national, Mussa Alareef, was quizzed by officials of the Porvorim police station for overstaying.
