With the arrest of Tanvir Ansari in the Mumbai serial blasts case, police on Monday claimed to have busted an important sleeper module of Lashkar-e-Taiba in the city.
Ansari, a Unani medicine practitioner at a local hospital, had allegedly undergone training in weapons handling and explosives at the LeT camps at Bahawalpur in Pakistan and Muzafarabad in Pak-occupied Kashmir in 2004, police said.
"Thirty-three-year-old Ansari is an ideologue and motivator for LeT members in Mumbai and adjoining areas," a senior official of the Anti- Terrorist Squad (ATS), which arrested him on Sunday night said.
Since his return to Mumbai from Pakistan in early 2005, Ansari has been dormant and resumed his job as a resident medical officer at Sabu Siddiqui Hospital in central Mumbai, the officer said.
But in the past few months, a top LeT leader had been pursuing Ansari to 'do something' in Mumbai, the official said quoting intelligence inputs. He will now be interrogated to find out his role in the serial blasts, the officer said.
A graduate from Nagpur, Ansari visited Tehran in 2004 on the pretext of some personal work. From Tehran he allegedly moved to Bahawalpur in Pakistan by road and attended a LeT camp in operating AK-47 rifles, stengun, grenade launchers and even stinger missiles, sources said.
