A criminal case was filed with Motijheel police station on June 13 in this connection.

Accused Salam is absconding.

Early this month, BB Motijheel office detected that 79 three-year national investment bond, each worth Tk 5 lakh, had gone missing from its securities section.

A probe committee formed later found assistant manager of securities section Abdus Salam Sikdar involved in the mischief.

The investigation unearthed that Salam issued 29 of the 79 bonds in favour of two organisations and an individual with fake signature and registration last month. The remaining 50 bonds are still to be traced.

Among the 29 fake bonds, 10 were issued in favour of Topoban Housing Ltd., 13 for IQ Trade International Ltd. and six for one Babul Ahmed. Topoban and IQ trade took a loan of Tk 61 lakh from Southeast and City banks against those bonds.

The central bank's inspection division is now probing how the banks gave loan without checking with the BB, and if anyone else was involved in the matter.

In a move to stop recurrence of such forgery, BB's Motijheel office has meanwhile reshuffled its bond distribution procedure

A high official at the Motijheel office said they will remedy procedural faults, if any, and take precautionary measures in the light of suggestions from the probe bodies.
