NEW DELHI: After tracking him for more than three years, security agencies have arrested Sayed Zabiuddin alias Abu Hamza , alleged Lashker-e-Taiba ultra and the Hindi tutor of 10 terrorists who carried out the audacious attack in Mumbai in 2008.The 30-year-old Ansari alias Abu Jindal, who hails from Georai area of Beed district in Maharashtra, was arrested on June 21 when he arrived in India from a Gulf country, official sources said on Monday.India had also secured an Interpol Red Corner notice against him in which he was accused of crimes involving the use of weapons, explosives and terrorism.With his arrest, the mysterious voice recorded during the conversation between 10 Lashker terrorists and their handlers in Pakistan has been identified, the sources said.According to the officials associated with the probe, Ansari had told Lashker terrorists carrying out attack in Nariman House to convey to the media that the "attack was a trailer and the entire movie was yet to come".The voice was that of Ansari and after this his activities were traced before he was finally nabbed in a Gulf country, according to officials.In the intercepted tapes, Ansari was also heard using typical Hindi words like "prashasan" (government) and was directing the terrorists to conceal their Pakistani identity and identify themselves from Deccan Mujahideen hailing from Toli Chowk in Hyderabad.His presence was also stated by Ajmal Kasab , the lone terrorist arrested during the Mumbai attack, in his deposition before a special court. He told the court that one person by the name of Abu Jindal had tutored 10 terrorists on how to speak Hindi.Missing since 2005, Ansari, who had undergone training at Indian Technical Institute in Beed, had a sudden rise in the ranks of Lashker-e-Taiba after he was indoctrinate by banned SIMI post Gujarat riots in 2002.The Central security agencies had quizzed many arrested terrorists to study the case of Ansari during which it came to light that he had been operating out of terror camps in Karachi and Pakistan-occupied Kashmir and was a key figure in the terror group's plan to carry out the strikes in the country's hinterland. ||||| New Delhi: The Delhi Police have arrested Abu Jundal, one of the key conspirators and handlers in the 26/11 Mumbai terror attacks. He is the first Lashkar-e-Taiba (LeT) operative to be arrested after Ajmal Kasab. The operative is believed to have guided and controlled the terrorists at the Nariman House from a Karachi control room throughout the night of November 27, 2008. 
 
 Here are the instructions he gave to the Mumbai attackers at the Nariman House: 
 
 - As long as you have hostages, the police can't do anything. 
 
 - If there is any problem, if the pressure builds up, shoot them. 
 
 - Do a good job… support your partner. 
 
 - Keep your morale high and say your prayers. 
 
 In a major breakthrough for security agencies involved in the 26/11 probe, Jundal is believed to have been deported from Saudi Arabia and arrested by the Delhi Police after he reached the national capital, with the entire slick undercover operation being kept under wraps, including Jundal's production and remand in a court last week. 
 
 According to officials, Jundal was one of the five handlers present in the control room in Karachi. He was directing terrorists carrying out the Mumbai attacks at every step. 
 
 Jundal was also responsible for weapon training the terrorists and familiarising them with the Hindi language. 
 
 He was involved in a blast in Ahmedabad in 2006 and the Aurangabad arms haul the same year. He was named in the 26/11 chargesheet and was considered one of the most wanted. 
 
 Kasab's testimony to Mumbai police names Jundal for seeing off the 10 attackers at Pakistan shore. Abu Hamza, Abu Qaafa and Lakhvi were the others. 
 
 After the Aurangabad arms haul, Abu Jundal fled to Pakistan. There he became closely involved with the activities of the LeT and eventually started working towards plotting the 26/11 attacks. The Mumbai crime branch which is probing the attack will now be taking a voice sample to further confirm that he indeed was one of the handlers. 
 
 Quite contrary to high profile busts, the Delhi Police stayed mum in this case. Sources said this was an operation managed at a diplomatic level and involved many central agencies. 
 
 Abu Jundal was an important LeT operative handling the groups operations in India. His arrest will be crucial not only for taking investigations into the Mumbai attacks forward but also for our agencies to find out the current structure, reach and plans of Pakistan-based terror groups. What they will also focus on is to find out what he was doing in Saudi Arabia for the last several months ||||| Image caption The attacks targeted luxury hotels and a railway station 
 
 Police in the Indian capital, Delhi, say they have arrested a key figure allegedly involved in the planning of the deadly Mumbai attacks of 2008. 
 
 Abu Jindal, also known as Syed Zabiuddin, has been remanded to police custody, a senior police official told the BBC. 
 
 He is being described as the "handler" of the 10 gunmen who carried out the deadly assault on targets in Mumbai. 
 
 The attacks claimed 165 lives. Nine gunmen were also killed. 
 
 The sole surviving gunman from the attacks, Mohammad Ajmal Amir Qasab, was convicted of murder and waging war on India in May 2010 and given a death sentence. 
 
 The 60-hour siege of Mumbai began on 26 November 2008, targeting luxury hotels, the main railway station and a Jewish cultural centre. 
 
 Relations between India and Pakistan hit rock bottom after India blamed the Pakistan-based militant group Lashkar-e-Taiba for the attacks. 
 
 After initial denials, Pakistan acknowledged that the assault had been partially planned on its territory and that Qasab was a Pakistani citizen.
– Indian police say they've arrested one of the masterminds behind 2008's dramatic Mumbai terrorist attack. Delhi police tell the BBC that Abu Jindal, aka Sayed Zabiuddin, was the "handler" of the 10 gunmen, and that his voice can be heard on recordings of conversations between the gunmen and their leaders in Pakistan. Sources tell the Times of India that he was nabbed last week while entering India from a "Gulf country"; an IBNLive report says he was deported from Saudi Arabia. "As long as you have hostages, the police can't do anything," Jindal allegedly advised the gunmen. But "if there is any problem, if the pressure builds up, shoot them." Jindal was originally from India, but allegedly was among five Lashkar-e-Taiba operatives who directed the attack from Karachi, Pakistan. He was also the one who allegedly gave the terrorists their weapons training, and taught them Hindi.
