DHAKA: A Bangladesh opposition activist and a businessman were remanded on Tuesday in police custody for questioning about the murder of a Japanese farmer, an attack claimed by the Islamic State group.
A court ordered the pair detained for 10 days over the shooting of Hoshi Kunio on Saturday in the northern city of Rangpur, the second foreigner killed in less than a week.
"A magistrate court in Rangpur remanded the two into custody for ten days for intensive interrogation over the murder," investigating officer Mamunur Rashid told AFP.
Rashid said police picked up the pair just hours after the murder, although they have not been named as suspects.
One of them, Rashedun Nabi Biplob, is a former leader of the main opposition Bangladesh Nationalist Party's (BNP) student wing and an active member, the party said.
Prime Minister Sheikh Hasina has blamed the BNP and its ally, Jamaat-e-Islami, for instigating attacks on the foreigners, a claim rejected by the parties.
Humayun Kabir Hira, the second man remanded, became friends with Kunio who leased farmland from Hira's brother-in-law in the town of Kaunia, according to police and another newspaper.
Three men riding on a motorbike shot the 66-year-old Kunio dead after stopping his rickshaw on a dirt road.
The extremist group later claimed responsibility for the killing, according to the SITE Intelligence Group, a US monitoring organisation, although experts are dubious.
IS also said it was behind the killing of Italian aid worker Cesare Tavella on September 28 as he was jogging in Dhaka's diplomatic quarter. No one has been arrested over that murder.
Experts say hard-line militants pose a growing danger in Muslim-majority Bangladesh, warning that a long-running political crisis has radicalised opponents of the government.
The assassination of four atheist bloggers since the turn of the year undermines the government's efforts to play down the threat posed by hardliners, experts say.
