Detectives have arrested former Chief Justice ABM Khairul Haque, who faces at least two cases, including one for declaring the verdict revoking the caretaker government provision from the Constitution.
The Dhaka Metropolitan Detective Branch (DB) of police picked him up from his residence in Dhanmondi around 8:30am on Thursday.
DB Joint Commissioner Mohammad Nasirul Islam confirmed this information.

Justice Khairul Haque, 81, was taken to the DB office on Minto Road in the capital. There are several cases against him, the officer said.
He was interrogated at the DB office until evening and produced in court with his hands cuffed behind him at 8:15pm.
The police showed him arrested in a murder case filed over the killing of Jubo Dal activist Abdul Kaiyum Ahad, 16, in Dhaka’s Jatrabari area on July 18 last year.
They did not seek his remand and prayed to the court for his confinement in jail until the investigation was complete.
Justice Khairul was not allowed to have a lawyer to represent him.
Outside the court custody, the BNP-leaning lawyers created a mob, forcing the prison van to take extra security measures.
Earlier, the BNP held a press conference and demanded exemplary punishment for the former chief justice. Mirza Fakhrul Islam Alamgir thanked the interim government for arresting the former chief justice, albeit belatedly.
He was sworn in as the 19th Chief Justice of the country on October 1, 2010. He retired on May 17 the following year, at the age of 67.

Ex-CJ faces 3 cases
The murder case was filed on July 6 this year by Ala Uddin, 61, a BNP leader from Noakhali.
The plaintiff accused Prime Minister Sheikh Hasina, Justice Khairul, and 465 others in connection with the killing.
The case also names 1,000 to 2,000 unnamed Awami League activists and 100 to 150 law enforcers as accused.
On August 15 last year, a case was filed against Justice Khairul at Fatulla police station in Narayanganj by Abdul Bari Bhuiyan, the general secretary of the Thana BNP and a former president of the District Bar Association.
In this case, he is accused of changing the verdict to annul the 13th Amendment to the Constitution and forgery.

Three days later, on August 18, Supreme Court lawyer Mujahidul Islam Shaheen filed a case against Justice Khairul with the Shahbagh police station over allegations of corruption and forgery of verdicts.
Out of scene for 11 months
While in the High Court Division, Justice Khairul gave the verdict in the Bangabandhu assassination case and the Fifth Amendment to the Constitution case.
Apart from this, he gave verdicts in various cases, including protecting the four rivers of Dhaka and declaring independence.
In 2013, he was appointed as the chairman of the Law Commission for a three-year term. After this term, the former judge was reappointed to the same position several times.
He resigned from the Law Commission on August 13 after the fall of the Awami League government and was no longer seen in public.
Caretaker government verdict
While in the Appellate Division, Justice Khairul gave the verdict to abolish the caretaker government system on May 10, 2011, and released the full verdict on September 16, 2012.
He stirred controversy for writing the full verdict after retiring from his post, but he insisted that there is no legal bar to writing a verdict after a chief justice goes into retirement. There have been many instances in the Appellate Division.
The parliament passed the 15th Amendment to the Constitution on June 30, 2011, and it came into effect on July 3.
On December 17 last year, the High Court restored the caretaker government system following two separate writ petitions.
In the judgement, the bench scrapped a part of the 15th Amendment that abolished the system and restored the provision for holding a referendum for bringing any amendment to the constitution.
On that day, the court also said the Appellate Division of the Supreme Court will make the final decision about the restoration of the caretaker government system, as review petitions on a verdict on the amendment are pending with the apex court.
The full verdict was released earlier this month, following which the National Consensus Commission tabled a fresh proposal on July 20, after three rounds of discussion over alternative proposals on the caretaker government.
The new proposal cuts the number of members in the caretaker government chief adviser selection committee from 13 to 5 and mandates that the general elections be held within 90 days of the dissolution of Parliament.
