DHAKA: Unknown assailants hacked a doctor to death and seriously wounded a professor in a single attack in western Bangladesh on Friday, local police said.

Sanaur Rahman, 58, a homeopathic doctor, was riding a motorcycle in Kushtia town with his friend Saif uz Zaman on Friday morning when they were attacked by at least three men, also on a motorbike.

While police said the assault bore similarities to a spate of previous attacks by suspected Islamists, they also said a personal dispute could be the motive for the killing.

“The style of murder bears similarity to the recent attacks by militants but we cannot yet be sure who actually did it as nobody has claimed responsibility,” Kushtia police superintendent Proloy Chisim said.

“We are primarily suspecting personal enmity,” he told AFP.

Zaman, a professor of Bengali literature at Kushtia’s Islamic University, was critically wounded and flown by helicopter to Dhaka, 240 kilometers away, for emergency treatment.

“We are probing whether there are some other links including a connection to militants,” police inspector Shahabuddin Chowdhury, who was at the scene, said.

Rahman’s family said he was a popular doctor who handed out free medicine to the poor.

“He used to distribute homeopathic medicine to villagers at his garden house every Friday. We don’t think he had any enemies,” his brother-in-law Obaidur Rahman said.

The pair were both fans of a classic musical tradition known as Baul, which is popular in Kushtia, with the doctor’s brother-in-law saying Rahman used to arrange concerts at his home.
