Dhaka: A case was filed with Sutrapur Police on Thursday night over the killing of online activist and Jagannath University (JnU) student Nazimuddin Samad, reports local news agency.

The Sutrapur police sub-inspector Nurul Islam filed the case at about 10:45pm accusing around five unidentified miscreants.

Inspector (Investigation) of the police station Somir Kumar Sutradhar was made the Investigation Officer of the case.

Earlier, a group of assailants swooped on Samad at Ikrampur of Sutrapur in the capital on 6 April night, and hacked and shot him indiscriminately, leaving him dead on the spot.

The police said the 28-year-old was killed as he posted against Islam on his Facebook page. Law enforcers were investigating whether Samad was murdered for his writing.

Samad had only recently arrived in Dhaka from the northeastern city of Sylhet to study law.

Deputy Commissioner Islam said police suspect the attackers had been monitoring the victim since before he arrived in Dhaka.

Nazimuddin was reported to have been an organiser of the Ganajagran Manch, a secular campaigning group.

Imran Sarker, who leads one of the Bangladesh’s largest online activist group, said Samad had joined nationwide protests in 2013 against top Islamist leaders accused of committing war crimes during the country’s war of independence.

‘He was a secular online activist and a loud voice against any social injustice. He was against Islamic fundamentalism,’ said Sarker, head of the Bangladesh Bloggers Association.

Samad had written against radical Islam in a number of recent Facebook postings.
