Detectives have arrested Additional Superintendent of Police (ASP) Sachin Moulik in connection with the killing of Golam Nafiz, who was shot dead during the August 4 protests in Dhaka’s Farmgate area.

Moulik, a 33rd BCS police cadre officer, was detained Thursday in Mahalchhari, Khagrachhari. He was previously attached to Mahalchhari-6 APBn following July’s uprising but had served as ADC of Tejgaon Zone during the fatal incident.

A tribunal had earlier issued an arrest warrant against him after Nafiz’s name became symbolic of the student-led movement. A photograph of the dying Nafiz lying on a rickshaw went viral, making him an icon of the protests. Nafiz was a student at Naval College in Dhaka.
