Biswas `indoctrinated' him in IS ideology and pushed him towards joining the terror organisation, say policeBengaluru police said that Salman Moinuddin, who was arrested by Hyderabad police on Thursday night as he was about to board a plane to Dubai, was in constant touch with Mehdi Masroor Biswas through Twitter.Police said Salman and Biswas, who was arrested last month for having alleged links with ISIS activists, were in constant touch and followed each other through their Twitter handles. Biswas had indoctrinated him in IS ideology and the war they were waging, and according to the police, he was on his way to join the ISIS when he was caught.“We found that Moinuddin was in contact with Mehdi before he was arrested. He has followed Mehdi on Twitter and they have exchanged tweets about IS,“ DCP Crime Abhishek Goyal said.“Mehdi has tweeted very seriously about the war which attracted Salman more towards the IS. By doing this, he gave a last push to Salman to jump into war,“ Goyal said. The accused had lived in the US for about four years including in Houston, Texas, and is said to have a MS degree in electronics from Texas Southern University.After he was denied a visa extension, Moinuddin returned to Hyderabad in October last year and during the last two months, lured several youth across the country to join ISIS and wanted to take them to Syria, police sources said.Sources said Moinuddin had planned to join his girlfriend Ayesha in Dubai from where they were to proceed to Syria via Turkey and establish links with ISIS militants.Ayesha is a British national and was formerly known as Nicky Joseph alias Nicole before she converted to Islam after coming in contact with Moinuddin.According to police sources, Moinuddin and Ayesha created various Facebook groups under fictitious names and spread the ISIS ideology with the intention of attracting followers.It may be recalled that Mehdi Biswas was arrested in December last year for his contacts with ISIS activists on Twitter. The police arrested him under Section 125 of IPC (for waging war against the government of any Asiatic power in alliance or at peace with the Government of India or attempts to wage such war or abetting waging of such war), Section 18 and 39 of Unlawful Activities (Prevention) Act and Section 66 of the Information Technology Act.Following his arrest, police have been gathering evidence to prove Biswas had supported ISIS and his messages on his Twitter handle had revealed his encouragement to people to join ISIS.
