The Anti-Corruption Commission (ACC) has barred former chairman of Prime Islami Insurance and Primeasia University trustee board Chairman MA Khaleque from leaving the country.
It issued a letter to the police on Wednesday, asking them to look into the matter.
The ACC has an ongoing investigation against Khaleque on charges of embezzling money from Prime Asia Foundation, Prime Islami Securities, People's Leasing and other institutions.
Khaleque was summoned by the ACC on Wednesday but he failed to comply and did not appeal for an extension either, said ACC spokesperson Pranab Kumar Bhattacharya.
He said, "A formal letter has been sent to the immigration department by the investigating officer and ACC Assistant Director Ataur Rahman to ensure that Khaleque does not leave the country."
The letter says, "It has been known from a trusted source that Khaleque is trying to leave the country with family members. For the sake of a sound and thorough investigation, it is essential to bar his foreign travels."
His Bangladeshi and Canadian passport numbers along with his national identification number have been mentioned in the letter.
On February 24, a notice was sent to Khaleque's house in the capital's Baridhara summoning him for questioning at the ACC on March 4.
