The three-member team reached the capital city yesterday and met Bangladeshi security officials at the police headquarters, Assistant Inspector General Md Moniruzzaman said.
In the meeting, they discussed information received so far during the interrogation of Neo-JMB militant Mahfuz, who was arrested along with three other militants by the Dhaka Metropolitan Police's Counter-Terrorism and Transnational Crime (CTTC) unit from Chapainawabganj district in northern Bangladesh on July 7.
Mahfuz, a top explosives specialist of neo-JMB, is on a seven-day remand in the Dhaka cafe attack case.
He allegedly supplied firearms and explosives for the cafe attack in which 22 people, including 17 foreigners, were killed.

Mahfuz who lost a hand while making bombs, thereby earning him his title 'Hatkata', was wanted by the National Investigation Agency (NIA) in India for the blast at Khagragarh in Burdwan district of West Bengal on October 2, 2014.
He wanted to visit India by this year and open a wing of "Neo JMB", counterterrorism officials were quoted as saying by the daily.
Sohel told the interrogators that he left India months after the JMB leadership removed him from the post of West Bengal JMB ameer and replaced him with Sajid, another Bangladesh-born militant, in 2014, the report said.
After his return to Bangladesh in December 2014, he got involved with pro-IS militants and played an important role in recruiting youths to the new brand of terror group, "Neo JMB" as police call it.
The Kolkata police team would stay in Bangladesh for the next couple of days.
Besides, a team of National Investigation Agency is supposed to arrive in Dhaka tomorrow to learn about Sohel's arrest, Moniruzzaman added.
