“The death of Gaibandha Sundarganj MP Manjurul Islam Liton was a pre-meditated murder,” said Quader. “Initially, it appears to be the cowardly work of sectarian forces.”
“The state will ensure that the religious extremists responsible will pay a high price for this crime,” he said.
“The attack was planned to coincide with New Year’s celebrations, coming just as Bangladeshis were beginning to celebrate.”
The family said that three men riding on a motorbike came to Liton's house on Saturday evening.
According to witnesses and police, he was shot twice in the chest and once in the arm.
The Awami League has blamed the Jamaat-e-Islami.
Liton is the second incumbent MP killed by gunmen after the 2005 murder of Awami League's Shah AMS Kibria in Habiganj.
A diploma engineer (marine) by training, Liton was a director of Ananda Group of Industries. It was his first tenure as a lawmaker.
He hit the headlines in 2015 after allegedly shooting a 9-year-old schoolboy in his constituency. He was arrested and later freed on bail.
