Members of Rapid Action Battalion (Rab) arrested six people, including a former Jubo Dal leader, in connection with the brutal killing of Rajshahi University professor Shafiul Islam.
Tipped off, they launched a drive in separate places and arrested the six from the capital and Rajshahi on Sunday, Rab sources said.
The arrestees include Ariful Islam alias Manik, former city Jubo Dal oraganising secretary, and also the alleged mastermind of the gruesome murder.
Prof Shafiul Islam was stabbed by some unknown assailants on his way home at Chouddapai near the RU campus around 3:30 pm on November 15. He succumbed to his injures at the Intensive Care Unit of Rajshahi Medical College Hospital half an hour later.
