The International Crimes Tribunal-2 on Thursday sent detained Jamaat acting secretary general ATM Azharul Islam to jail.
It passed the order after hearing both the defence and the prosecution about his bail petition.
The tribunal said that it would give its order on his bail petition on Sunday and asked the prison authorities to produce him before it on the day.
Azhar, the 11th man to face war crimes charges, was arrested on Wednesday following an order from the tribunal.
The Detective Branch of the Dhaka Metropolitan
Police arrested Azharul at his Elephant Road residence in the city.
The DB kept him at its office and took him to the tribunal housed at the Old High Court building on Thursday at around 11.15 AM.
On Wednesday, the prosecution brought several allegations of war crimes including murder, mass killings, loot, arson, rape, forced conversion to Islam and deportation against Azhar.
The prosecution sought Azhar’s detention saying as the influential acting secretary general of the Jamaat, he was trying to destroy war crimes evidences at home and abroad.
The prosecution said that he might organize religious militants to create instability in the country.
Abdur Razzak, the chief defence counsel of Jamaat leaders facing war crimes trial, moved his bail petition on Thursday and said Azhar was arrested in a false, fabricated and politically motivated case.
He submitted that his client was arrested on September 19, 2011, was shown arrested in 11 cases and was released on August 16 and that there was no possibility of for him to threaten any of the witnesses or victims as the investigation against him started on April 16 while he was in jail.
Razzaq submitted that following his release on August 16, Azhar was kept under house arrest until he was arrested again on August 22 as the government had the intention to keep him in jail as he is the acting secretary general of Jamaat.
He submitted that the International Crimes Tribunal was used to suppress him.
He also submitted that his client sought bail as he had been suffering from heart diseases, diabetes and severe pain.
Opposing the bail prayer, prosecutor Zead-Al malum argued that the prosecution prayed for his arrest after it received several allegations of war crimes against him and that the prayer was not politically motivated.
He also argued that the International Crimes (Tribunals) Act, 1973 did not grant bail to the other accused during the investigation and trial though the rules under the law recognized bail as a privilege of the accused.
The prosecutor submitted that there was no ground to grant him bail and prayed to reject his bail petition.
Azhar was the president of the Rangpur unit of the Islami Chattra Sangha, the student wing of Jamaat in 1971.
Earlier, the tribunal rejected two petitions of Jamaat nayebe-amir, Delwar Hossain Sayedee, one seeking shifting the date of submitting a list of 20 defence witnesses, out of 48 that the defence had already submitted, and the other to adjourn defence proceedings until his recovery from ailments.
