Unidentified assailants have hacked the blogger to death and seriously injured his blogger wife Rafida Ahmed Bonya on Thursday night inside Dhaka University campus.
His father, professor Ajay Roy, filed a case of murder with Shahbagh police on Friday and said extremists were behind the murder and “Jamaat(-e-Islami) has backed them”.
The case did not name anyone and was filed against unidentified assailants.
Islamist zealots have been threatening Avijit, a bioengineer and a naturalised US citizen, for his active campaign against Islamist radicals.
He was a regular bdnews24.com columnist and the founder of the popular blog, Mukto-mona.
