The members of his family believed Mohammad Al Farooq, 17, had been killed at the Shapla Chattar on May 5 last year following a police crackdown on Hifazat demonstrators.
His name had, in fact, figured on the list of the missing prepared by Hifazat, a Chittagong-based radical organisation.
But Detective Branch sleuths traced Farooq on Wednesday night to the Miskin Shah Mazar next to the Ghani Bakery in the port city of Chittagong.
He is the second child of Solaiman Bin Mobarak, a resident of the Muradnagar Thana area in Comilla.
Before going missing last year, Farooq used to be a student of the Unmul Kora Academy in Dhaka’s Badda.
The members of his family had told police that he had gone missing after taking part in the Hifazat rally.
But Farooq has said after his return that he was at his Muradnagar house in Comilla on the day of the demonstration.
He said he had not attended the rally that day while admitting he was a Hifazat supporter and a follower of its Amir Shah Ahmed Shafi.
Hifazat had held a sit-in at the Shapla Chattar in Motijeel that day, leading to large-scale vandalism and arson at Paltan, Baitul Mokarram, Bangabandhu Avenue and Motijheel from afternoon to late evening.
Police flushed out the Hifazat supporters occupying the place at night, long after the time allotted for the rally had passed.
The Hifazat and the BNP claimed that scores of people had been killed in the police action.
Chittagong’s Detective Branch sub-inspector Santosh Kumar Chakma told bdnews24.com: “Farooq had not kept in touch with his family after going missing. So, his family had taken it for granted that he had been killed that day.”
On Aug 31, Farooq called his mother from an unfamiliar number to say that he was fine and became incommunicado again.
