Police have arrested the son-in-law of Sultan Shahriar Rashid, an executed killer of Bangabandhu, as he allegedly made derogatory remarks about the Father of the Nation and glorified his killers on Facebook.

Fuad Zaman was arrested from Hatirjheel area around 10:00pm on Wednesday, Masudur Rahman, deputy commissioner (media) of Dhaka Metropolitan Police told The Daily Star.

He was accused in a case filed with Dhanmondi Police Station on August 23 by Nazmul Hasan Piyash, a member of Ahsanullah Science and Technology University wing of Bangabandhu Engineers Council.

A Dhaka Court yesterday granted a three-day remand for him in the case filed under Information and Communication Technology Act. 

Fuad took to Facebook around 7:15am on August 15 -- the anniversary of Bangabandhu's assassination and National Mourning Day -- when he wrote derogatory remarks on the gruesome killing of Bangabandhu Sheikh Mujibur Rahman, and openly supported the killers.

His Facebook post is defamatory, derogatory and instigates anarchy in the society, the complainant wrote.

A police official said the accused in primary interrogation admitted that he wrote the derogatory remarks out of vengeance as his father-in-law was executed.
