Bangladesh police arrested former Industry Minister Matiur Rahman Nizami from his residence in Dhaka in a graft case on Sunday.
Nizami also heads the Jamaat-e-Islami, the country's largest Islamic party.
Earlier, two former cabinet ministers of the Bangladesh Nationalist Party-led alliance government, Abdul Mannan Bhuiyan and Shamsul Islam were sent to Dhaka Central Jail after they surrendered before the court.
Former Prime Minister Khaleda Zia and her son Koko were arrested in September last year in the same case of alleged underhand deal of Tk14.56 crore for giving container handling contract to a private company while she was in power.
The Anti-Corruption Commission filed the case accusing 22 persons including ex-PM Zia and her five former Cabinet colleagues.
