The police have said that a university professor was hacked to death in Bangladesh and have related the incident to that in which secular bloggers and atheists have been suspiciously killed by Islamist extremists.
The 58-year-old AFM Rezaul was a professor of English in the north-west based Rajshahi University.
Machetes were used in the attack against him, carried out by assailants who could not be identified as he headed home from the university.
In the year 2015, prominent secular bloggers were also attacked and killed using machetes.
However, the colleagues to the killed professor say that he was not a blogger and that he has not written anything that is not controversial.
The police are of the opinion that the incident may have been triggered by Islamist extremists since he was an active member in cultural activities.
Siddique had founded a music school and edited a literary magazine, his family told the BBC.
Nahidul Islam, deputy police commissioner, spoke to AFP news agency that the location of the music school is Bagmara. The outlawed Jamayetul Mujahideen Bangladesh (JMB) Islamist group had its bastion here.
The JMB members were arrested due to assaulting an Italian Catholic priest last year.
The wife of the professor said that she was not aware that her husband’s life was in danger.
“As far as I know, my husband didn’t have any personal enmity with anyone. I can’t believe that he has been murdered,” she told the BBC.
The campus students have protested against the death of their teacher and have demanded that the perpetrators be brought to book.
