Sheikh Hasina's son Sajeeb Wazed Joy targets Pakistan for several attempts made to kill Bangabandhu in prison

He made the remark ahead of the 50th anniversary of Bangabandhu's jail-free day.

“After a long nine-month bloody war against the Pakistani barbaric junta, the Bengali nation achieved its much-desired victory on December 16, 1971," Joy was quoted as saying in an article as quoted by The Economic Times.

"The whole country got decorated with red-green flags in the air everywhere. But there were the piles of the bodies of three hundred thousand martyrs and the sufferings of more than four lakh tortured mothers and sisters, on the one hand, there were also burst of joy from the freedom of the Bengali nation from the Pakistani monsters amid the mourns of losing the near and dear ones," he said.

"But even after such momentum, the Pakistani junta carried out an attempt to kill the founder of Bangladesh, Bangabandhu Sheikh Mujibur Rahman in a Pakistani jail,” he said.

He said the purpose was to break Bangabandhu physically and mentally in the midst of natural adversity along with the loneliness of the dark solitary confinement.

"Later, Bangabandhu was kept in solitary confinement for the death row convicts in Mianwali Jail in North Punjab. He was kept under constant surveillance in the jail. Therefore the Pakistani junta plotted to assassinate the undisputed leader Sheikh Mujibur Rahman in jail," he said.

"Through 1971 Mujib was shifted from one to another jail in Pakistan. Apart from killing attempts at Mianwali, Faisalabad and Sahiwal, there was another conspiracy to kill Bangabandhu in a solitary confinement cell in the dark cell of Lyallpur Jail in North Punjab, about 150 miles from Rawalpindi. The conspiracy continued in the name of a secret trial. Far from being a prisoner, he was not even allowed to speak alone with his own lawyer in secret courts. Even a transmitter was placed in Bangabandhu's chair so that the Pakistani junta could hear whatever he said," Joy wrote.

"Before the surrender of the Pakistani forces at Suhrawardy Udyan in Dhaka, on the night of December 15, the Pakistani junta plotted to create chaos among the prisoners through which they aimed to kill Mujib," he said.

Joy said the return of Bangabandhu to his home fulfilled the meaning of the independence of the Bengali nation.
