L-R: Abu Bakkar and Wazed Khan

Yet another Lashkar-e-Taiba (LeT) operative, this time an explosives expert, and his local aide were arrested by Rab in the city's Uttara early yesterday with a huge amount of explosives and bomb making materials.
It was the first arrest of any LeT bomb expert in the country, according to Commander Mohammad Sohail, Rab's legal and media wing director.
He said the battalion had recovered 30 kilograms of high explosive with the capacity equivalent to trinitrotoluene (TNT) and six bottles of liquid chemical from their possession.
However, it couldn't be learnt whether the Pakistan-based militant outfit is plotting any bomb attack in Bangladesh or neighbouring country.
The LeT man, Wazed Khan alias Zafar alias Salman, 27, is a Pakistani national.
His aide Abu Bakkar Siddique, 49, is a stranded Pakistani and a resident of Turag Housing in the city's Mohammadpur area.
The Rab arrested LeT members first on February 28, said Sohail. So far nine operatives of the internationally banned organisation have been caught by the battalion and of them, four are locals and the rest are Pakistanis.
A joint team of Rab intelligence wing and Rab-1 made yesterday's arrests around 12:15am from Abdullahpur, Uttara after a tip-off from LeT man Maulana Mohammad Imran, another Pakistani arrested on September 29 in Narayanganj.
Another Rab team recovered huge explosives from a house at Shahibagh, Savar on October 6 acting on Maulana Imran's information, Sohail added.
Wazed Khan came to the country on April 7 this year with a tourist visa on orders from a top LeT leader, Abdul Kuddus alias Abdul Karim Tunda alias Babaji.
Wazed while a Lahore Islamic University student received training on explosives from Abdul Kuddus.
Sohail said, Abdul Kuddus alias Tunda, who is now detained in a Pakistani jail, visited Bangladesh and held meetings with JMB chief Shaikh Abdur Rahman, who was later executed.
In Bangladesh Mohammad Imran received Wazed and introduced him to Bakkar, the owner of Anika Chemical, Sohail said adding, Bakkar arranged Wazed's accommodation at his residence in Turag Housing.
Maulana Imran and Bakkar provided Wazed with different chemicals to produce explosives. The bomb expert was asked to handover the finished explosives to Maulana Imran, said Sohail.
During interrogation, Bakkar admitted he had bought the chemicals from Lalbagh, Old Dhaka.
In 2007 Bakkar got acquainted with Maulana Imran while Bakkar was residing at a rented house in Mirpur. The two became involved in the business of fake Indian currency.
Several Pak operatives of LeT are active in the country and they have made explosives. But their targets are yet to be known, said Sohail.
The Pak operatives were not given the address of the other LeT teams for their safety. The law enforcers could not learn how many of them are now in Bangladesh.
Sohail said the LeT has no unit in the country. But it is trying to use the country as a haven for running business of fake currencies and making explosives.
Rab personnel also seized passports of the two detainees. The passport of Bakkar shows he made eight trips to Pakistan and three trips in India recently.
