The probe is being made by a three-member body headed by A M Moasser, director (inspections) of T&T Board. The two other members are Deputy Director Md. Shawkat Ali and Divisional Engineer Md. Abdur Rahim.

Sources at Barisal T & T office said, during the first phase of investigation done in the first half of last month, the team detected about Tk 2.5 core revenue loss at the divisional office.

After the first phase of probe, eight employees including three sub-assistant engineers were suspended and another five transferred from Barisal for involvement in irregularities and corruptions.

The second phase probe was initiated as the team, during its earlier investigation, got clues on more about Tk 14 core irregularities, done in last 14 years, the sources said.

Following order by higher authorities, the team came to Barisal again on Thursday and started the second phase of investigation.

But members of the team declined to make any comment, saying they will complete the probe in a week and submit their report to higher authorities in Dhaka.
