The victim, Nasir Uddin, sustained 9 percent burns on his hands, chest and
thighs and he was taking treatment at Sadar Hospital, said Dr Md Khalil Ullah of the hospital.
On August 2, Nasir filed a case against a local – Joynal - who allegedly raped his wife several times through blackmailing her. Joynal used to violate the victim threatening to make the video of the rape incident viral on social media.
The accused also fined a counter misappropriation case against him and the witnesses of his case.
The victim’s mother said Nasir joined the human chain in front of the Naokhali Press Club protesting separate incidents of rape in the district.
Around 2am on Monday, a group of 6-7 people hurled acid on Nasir when he came out of their residence to respond to the call of nature.
Officer-in-charge of Char Jabbar Police Station Shahed Uddin said no complaint has yet been lodged in this regard.
