Hummam Quader Chowdhury, son of executed war criminal Salauddin Quader Chowdhury, returned home early Thursday, nearly seven months after he was allegedly picked up by unidentified men.

His uncle Gias Uddin Quader Chowdhury told The Daily Star yesterday that Humman was left near Sultana Kamal Mohila Krira Complex in Dhanmondi area around 2:30am. He went home from there.

“He [Hummam] couldn't tell us who had picked him up or where he was kept or who left him [on early Thursday],” he said, adding that “Hummam's physical and mental condition was not good”.

Gias, also a former BNP lawmaker, said Humman was staying at one of his relatives' home and that he would see a doctor tomorrow.

On August 4 last year, Hummam, also a central BNP leader, was “picked up” from a court compound in Old Dhaka. He had been traceless since then, said his family members.

Meanwhile, Amnesty International and Human Rights Watch have said, “Bangladeshi authorities need to immediately reveal the fate and whereabouts of two other men held in secret detention”.

“Two other men -- Mir Ahmed Bin Quasem and Abdullahil Amaan Azmi -- were also taken in August 2016 in separate incidents and have not been heard from since. They should either be charged or released without delay,” the global rights bodies said in a joint statement yesterday.

On August 9 last year, Ahmed, son of top Jamaat leader and executed war criminal Mir Quasem Ali, was allegedly picked up by some unidentified men from his Mirpur DOHS home in the capital.

On August 22 the same year, Azmi, son of late war criminal and ex-Jamaat-e-Islami ameer Ghulam Azam, was also allegedly picked up by some unidentified men from his Boro Moghbazar residence in the city.
