A former Bangladesh Navy Officer and nephew of BNP chief Khaleda Zia was on Thursday arrested and remanded to a four-day police custody by a court in connection with the 2004 grenade attack on Prime Minister Sheikh Hasina.
Former Lt Col Saiful Islam Duke was sent to police custody after hours of interrogation by Criminal Investigation Department (CID) officials for his suspected links to the attack in which 24 people were killed.
"Additional Chief Metropolitan Magistrate Mohammad Ali Hussain allowed police to quiz him for four days against our prayer for seven days," a CID official said.
He said Duke was personal secretary to the then prime minister Zia while he helped a prime suspect flee the country following the attack.
Duke's arrest came a week after Home Minister Sahara Khatun said the process was underway to expose to justice "masterminds" of the deadly grenade attack as investigators found several opposition politicians, intelligence agency bosses and militants to have jointly drawn the "blueprint'.
The state-run BSS news agency quoting officials earlier said the investigators found proof of "direct involvement" of Zia's now expatriate elder son and party’s senior vice chairman Tarique Rahman in the attack.
Quoting an unidentified senior police officer, the report said Rahman, who now stays in London, the then junior home minister Lutfuzzaman Babar ex-deputy minister Abdus Salam Pintu of the Zia's BNP-led government were directly linked to the planning of the attack.
