Rab sources claimed that Ahsan Habib Babu, general secretary of Durgapur upazila BCL, was an 'outlaw' and he was killed in an 'encounter' with them.

Rab arrested Babu from Taherpur Bazar and the shootout took place when they were returning to Rajshahi, they added.

Babu was killed when he tried to flee away.

The victim's father Afsar Ali, vice-president of upazila Awami League, said Rab members shot his son dead minutes after he was arrested.

Quoting witnesses Afsar said Babu was shot at his head and there was no shootout as claimed by Rab.

Local AL protested the incident and called a dawn to dusk hartal at Durgapur.

AL sources said they will file a murder case in this regard today.
