Yasin Bhatkal, founder member of the Indian Mujahideen who was arrested from Indo-Nepal border on Wendnesday, has strong links to West Bengal. He personally visited the state a number of times to collect explosives sneaked in through Bangladesh.
He was also arrested in the state capital Kolkata in 2009 but walked free after cops failed to identify him.
Moreover Anwar Mullick (42), a courier who ferried fake currency and explosives across the Bangladesh border and was arrested on July 7 by a Special Task Force of Kolkata Police, reportedly stated during interrogation that he had been supplying explosives to Bhatkal since 2010, which was used in a number of blasts in the country.
Bhatkal is accused in a series of blasts since 2007, including the German Bakery blasts and blasts in Bangalore and Hyderabad.
"We are looking to interrogate Yasin Bhatkal as soon as possible and will definitely send a team. He frequented West Bengal to get his supply of explosives and had a strong network here. He will shed light on operatives who supply explosives and logistics," said a senior official of the STF.
"We have missed him once. Now we want to see what he has to say," the officer added.
It was in 2009 when police in Kolkata arrested Bhatkal but failed to establish his identity. Bhatkal used a false name and claimed to be a resident of Kolkata. He even spent time in jail but later made bail.
Kolkata police sources stated that interrogating Bhatkal is also necessary since he is close to IM leader Amir Reza Khan, who is still at large.
Both Amir and brother Asif Reza Khan are from Beniapukur in the state.
Sleuths also believe that Bhatkal has vital information regarding the American Centre attack and shoe baron Partha Roy Burman abduction case.
Sources stated that Bhatkal visited Bengal twice in 2010 to get his consignment of explosives. He also dealt with fake currency rackets operating in the state. Explosives and fake currency are brought to India through the porous border the state shares with Bangladesh.
