DHAKA (TIP): Detectives in Bangladesh’s capital have arrested two suspects in connection with the killing of a secular blogger by suspected Muslim militants last week.

Dhaka Metropolitan Police spokesman Muntasirul Islam said Friday they picked up Saad-al-Nahin and Masud Rana, both suspected members of Ansarullah Bangla Team, a group blamed for some previous attacks on bloggers.

On Aug. 7, at least four men posing as tenants entered an apartment building and hacked to death the 28-year-old Niladri Chottopadhay Niloy, in the fourth such deadly attack this year.

Police would not provide other details about the arrests and whether the two were suspected of being directly involved in the attack.

The blogger’s wife, Asha Moni, has filed a murder case against four unnamed persons.
