In a memorandum submitted to the president and chief adviser of caretaker government at his Bangabhaban office, the organisation leaders made the request.

They also declared a sit in programme with 50,000 three-wheeler drivers in front of Anti-Corruption Commission on November 18 if the corrupt persons are not arrested.

A procession of around 200 activists of the organisation tried to reach the president but police barred them at Gulistan and the leaders handed the memorandum to an official of the president's office.

The former BNP government made manipulations in selling CNG-run three wheelers, the memorandum signed by the organisation President Shah Alam Chowdhury and General Secretary Idris Ali said.

Blaming a group of officials of Bangladesh Road Transport Authority (BRTA), the leaders said the buyers were compelled to purchase each vehicle at Tk 5 lakh instead of its real price Tk 1.7 lakh.

The government officials, with the backing of Huda and Tarique Rahman, looted Tk 396 crore from the sector, the memorandum reads.

Besides, they made Tk 2 crore by compelling the buyers to purchase stickers at Tk 5,000 for each vehicle.
