NEW DELHI: Indian Mujahideen, the homegrown terror outfit, had split into two groups with two senior members - Ahmad Zarar Siddibappa alias Yasin Bhatkal and Mohammad Qateel Siddiqui -- running 'parallel leadership' in the outfit due to ideological and operational differences between them, IM's acting chief Tehsin Akhtar alias Monu has told his interrogators. Qateel, who was killed in Pune's Yerwada jail on June 8, 2012, had even pulled some members of the main leadership - led by Riyaz Bhatkal and Yasin Bhatkal -- in his group, claimed Tehsin, who was arrested by intelligence agencies and Delhi Police's special cell from the India-Nepal border on March 25. TOI accessed exclusive details of his interrogation with the security agencies. Qateel, according to Tehsin, had many reasons to part ways with Yasin Bhatkal, who had recruited him in the outfit. One of the reasons Qateel and Mohammad Adil alias Ajmal (Pakistani national who was involved in Jama Masjid attack on September 19, 2010) were miffed with Yasin was that "Qateel and Adil wanted freedom to indulge in robbery etc while Yasin was not in favour of these activities", Tehsin said,. The members of Darbhanga module of IM who had become part of Qateel's group included Gayur Ahmed Jamali and Farookh, apart from Mohammad Adil. Farookh and Gayur were arrested by special cell of Delhi Police in November-December 2011. Giving details about their meeting at the Dharampur hideout in Samastipur (Bihar) after a failed attempt to attack tourists in Delhi's Paharganj on August 1, 2010, Tehsin said, "When I came to Dharampur hideout after a gap of about 10-12 days, I found that Adil and Qateel had come back. They were looking devastated. Yasin, however, was not to be found. I came to know that they had gone to Delhi to fire at tourists but their operation didn't go as planned and Qateel had suffered injuries. They seemed miffed with the behaviour of Yasin. They also didn't answer properly regarding Yasin's probable return to Samastipur." Qateel, who had gone to Delhi with Waqas and Yasin, to carry out strikes on tourists in August 2010, had a bullet injury in his hip. Tehsin kept visiting the hideout looking for Yasin but couldn't find him. Qateel then made him talk to Yasin over phone to which Yasin told Tehsin that he would return soon, said sources. According to Tehsin, when Yasin came back to Bihar in the third week of August 2010, he told the members that he had been diagnosed with dengue in Delhi. Talking further about the differences between Yasin and others, Tehsin said, "By that time (return of Yasin from Delhi), Adil was distraught and he was not following the orders of Yasin and was apparently in rebellion mode. Qateel was also following Adil in his protests against Yasin. After 2-3 days, Yasin told Adil to go back to Nepal." After this, Qateel took part with Yasin in September 19, 2010 Jama Masjid attack in Delhi in which Mohammad Adil and other members also participated. Qateel and Adil were reportedly the ones who had fired on tourists. Giving details of further dispute between Yasin and Qateel, Tehsin said, "In the beginning of November 2010, Farookh left the Sara Mohanpur hideout (in Darbhanga). This was because Gayur had enticed Farookh from the fold of Yasin to attach him with Qateel (who was, by this time, leading a parallel leadership from Yasin)." Tehsin added, "Gayur, however, never tried this tactic with him as he was convinced that the he (Tehsin) was completely dedicated to Yasin. Gayur tried to maintain relations with both the camps -- Yasin's camp and Qateel's camp -- but Yasin had read his true colours and had even informed Tehsin about his beliefs in this regard." Sources said Qateel was never seen after this with Yasin. He was not found to be involved in December 7 Varanasi Sheetla Ghat blast and July 13 Mumbai serial blasts. Tehsin claimed that towards the end of April 2011, Danish (of Darbhanga module) was also not interested in staying with Yasin due to some ideological differences. However, sources said, it was not known whether he joined Qateel's group or not. Tehsin said he did not hear about Qateel after that. Qateel was allegedly killed in Pune's Yerwada jail by two inmates on June 8, 2012. Apart from all the differences, Yasin had recruited Qateel in the outfit and was considered to be his close friend. After his murder in Pune jail, Yasin took revenge for his murder and carried out serial blasts in Pune on August 1, 2012.
