Bangladeshi workers, who were working at the copper factory owned by Inshaf Ibrahim, one of the suspected Sri Lanka attackers, are returning.

A source seeking anonymity said that there were more than 10 Bangladeshi workers and all of them are coming back to Dhaka on Friday.

In that factories over 30 Indians also worked and all of them went back to their countries, the source said.

He said most of the Bangladeshi workers hailed from the district of Tangail.

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.

 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.

The brother's father, Mohamed Ibrahim, was arrested as police investigate those behind the attacks, police 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.

The Reuters report quoted a Bangladeshi worker identified as Sarowar at Ibrahim’s copper factory.

“He was kind, unlike like many bosses. I was happy working for him.

“He is gone. What do I do now?” he was quoted saying

Meanwhile, tourists including Bangladeshis are gradually leaving the Indian Ocean island country devastated by the Easter Sunday bombings.

As many as 40 foreigners, including 8-year-old Bangladeshi boy Zayan Chowdhury, were among the more than 200 people killed in the coordinated bombings in luxury hotels and churches.
