DHAKA: Bangladesh police have arrested a suspected militant charged with the murder of a professor amid a surge in deadly attacks against liberal activists and other minorities in the South Asian nation, a senior officer said on Tuesday.
Rezaul Karim Siddiquee, 58, an English professor at Rajshahi University, was hacked to death on his way to work last month. The militant Islamic State (IS) group claimed responsibility for the killing of the professor.
Police however arrested a suspected member of the banned local militant group, Jamaatul Mujahideen Bangladesh, thought to have been lying low since six of its leaders were hanged in 2007.
"The suspect was arrested on Sunday," Rajshahi city police Chief Mohammad Shamsuddin said.
The Muslim-majority nation of 160 million people has seen a series of attacks over the past year in which atheist bloggers, academics, religious minorities and foreign aid workers have been killed.
Al Qaeda in the Indian Subcontinent has also claimed responsibility for some of the attacks, including the killing of two gay rights activists last month. But police say home-grown militant groups are behind the violence.
Dozens of Jamaatul Mujahideen members have been arrested and at least five killed in shootouts since November, as security forces step up a crackdown on militants.
In 2005, the Jamaat-ul-Mujahideen set off nearly 500 bombs almost simultaneously on a single day, including in Dhaka. Subsequent suicide attacks on courts killed 25 people and injured hundreds.
