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 today.
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. MORE
