One of the five Gulshan attackers whose identity had remained unknown was identified by Dhunat police in Bogra yesterday.

The young man identified as Shafiqul Islam Uzzal, 25, was son of Badiuzzaman, a farmer, of Tithulia Chollishpara village of Dhunat upazila, said Arifur Rahman Mandol, additional superintendent of police.

The attacker was a graduate and used to teach at a kindergarten in Ashulia on the outskirts of the capital. His sister-in-law identified him when she saw pictures of the attackers published by SITE Intelligence on Facebook, the police official said.

The family told police that Uzzal had remained out of contact with them since January.

Another Gulshan attacker was identified by Bogra police on Sunday as Khairul Islam Payel, 20, son of a day labourer.

Social media users and friends identified the three others seen in pictures released by SITE Intelligence soon after the pictures went viral. They were Nibras islam, Rohan Imtiaz, and Meer Sameh Mubasheer -- all from affluent families.
