Dhaka, April 9 (IANS): Bangladesh police on Saturday said they are yet to find any blogs written by murdered online activist Nazimuddin Samad, but have found a diary he maintained since 2009.

An Al Qaeda linked group reportedly claimed the killing of Nazim, 27, for his "anti-Islam views", but police said they have not found anything like that in his writings, bdnews24 reported.

Nazim was ambushed on Wednesday night at the capital’s Sutrapur while he was on his way home from evening classes at the Jagannath University.

Assailants attacked him with machetes before shooting him.

Nazim, who had moved to capital Dhaka from the eastern district of Sylhet a few months ago, was involved with Ganajagaran Mancha, the popular movement raised to ensure maximum punishment for 1971 war criminals.

He was vocal on social media against religious fanatics.

Last year, suspected militants hacked to death at least four atheist bloggers and a secular publisher in one of a series of targeted killings in the Muslim-majority country.

Police arrested members of a banned group called Ansarullah Bangla Team over those murders, but none has yet been prosecuted.

“The government is creating impunity to all the offences by not bringing the perpetrators to book," Maruf Rosul, one of the Ganajagaran Mancha activists, told the Guardian.

“Instead of pointing blame at different outfits, the government should identify the perpetrators and bring them to justice.”
