Bangladeshi workers, who were working at the copper factory owned by one of the suspected Sri Lanka attackers, have been questioned by the police upon their arrival at Dhaka.
A Malindo Airlines flight carrying the workers landed at Hazrat Shahjalal International Airport on Friday (Apr 26), immigration police sources told Bangla Tribune.
They were interrogated by members of several law enforcing agencies, including the immigration police.
The workers were employed in the copper factory owned by Inshaf Ibrahim, an alleged perpetrator of the Sri Lanka bombings.
Local and international media outlets have quoted the Sri Lankan police saying that the bombs were made at that factory.
Thirty-three-year-old Inshaf detonated his explosive device at the busy breakfast buffet of the luxury Shangri-La hotel, Reuters reported on Wednesday citing a close source to his family.
According to Sri Lankan media, his 31-year-old brother Ilham was also one of the suicide bombers of Sunday attacks, says the Reuters report.
Their father, Mohamed Ibrahim, was arrested as police investigate those behind the attacks, police said.
Sri Lankan authorities, however, have not released the identities of any of the bombers, and police did not respond to request for comment, it said.
Ibrahim, a wealthy spice trader and pillar of the business community, had six sons and three daughters. He was admired by many who knew him.
Meanwhile, Indian daily Hindustan Times and British daily The Guardian reported that the mastermind behind the series bombings at Colombo Mohammad Hashim alias Jahran Hashim is in touch with the pro-IS militants in Bangladesh.
The international dailies quoted Indian detective agencies saying that the information they got the information from an IS member they arrested last year.
Bangladeshi law enforcers, however, denied receiving any such information from India.
A Counter Terrorism and Transnational Crime (CTTC) unit source said that they are on the alerts and have also taken all the threats into consideration.
The source said that the Sri Lanka attack has “inspired” the Bangladeshi militants but they don’t have the resources to carry out any attack.
