Unidentified criminals hacked a primary schoolteacher to death and injured his wife early yesterday after entering their house in Pirojpur's Nazirpur.
The victim, Shamiron Majumder, 45, was an assistant teacher of Paschim Baniary Government Primary School in the upazila. He was the son of Shaylendranath Majumder in Paschim Baniary village.
His wife Swapna Majumder was undergoing treatment at Khulna Medical College Hospital.
The motive behind the attack could not be known immediately.
However, Walid Hossain, superintendent of Pirojpur police, said the attack might have happened over a land dispute.
Quoting Swapna, neighbours said criminals dug a hole into the earthen floor of Shamiron's house and one of them entered the house around 2:00am. He then stabbed Shamiron and his wife. Their three children were also in the same room.
The attacker along with his accomplices, who were outside the house, left the spot, but they did not take away anything.
Hearing their screams, neighbours rushed to the spot and took the injured to Nazirpur Upazila Health Complex. As their condition deteriorated, they were shifted to Khulna Medical College Hospital where doctors declared Shamiron dead.
Police picked up Montu Howlader, 30, from Paschim Baniary village for interrogation in connection with the attack, SP Walid said.
