Finally, the seven people, including four policemen, accused in the Maj (retd) Sinha murder case were taken into Rab custody from jail for interrogation.
It happened yesterday after the authorities appointed Rab Assistant Director Khairul Islam as the investigation officer (IO) of the case, replacing the previous one.
Though the seven accused were placed on a 7-day remand each by a Cox's Bazar court on Wednesday, Rab did not take them in custody.
Rab officers have also not interrogated the three top accused -- suspended officer-in-charge of Teknaf Police Station Pradeep Kumar Das, Inspector Liaqat Ali and Sub-Inspector Nandadulal Rakhshit.
"Changing an IO of a case is absolutely routine work," said Ashique Billah, legal and media wing director of Rab.
He added that the authorities decided to employ a much more experienced officer who has vast experience in solving sensitive and critical cases.
Asked whether the interrogation was delayed for the appointment of a new IO, he said no.
"The previous officer took the time because he thoroughly studied the case, talked to the witnesses, visited the place of occurrence, and talked with Sefat and Shipra. He was taking meticulous notes for a neutral investigation," Ashique said.
A team of Rab-15 took the seven accused from Cox's Bazar prison around 10:00am, reports our correspondent in the district.
Besides the four policemen, the three other accused are Nurul Amin, Nijam Uddin and Ayachh Uddin. They were named as witnesses in the two cases filed by police after the killing.
The accused were taken to Cox's Bazar Sadar Hospital for check-ups around 10:35am, said resident physician Saheen Abdur Rahman.
No health issues were found during the examination, he added.
PROBE COMMITTEE VISITS SITE
A four-member committee formed by the home ministry yesterday visited Marishbunia village in Teknaf and talked to several villagers.
Shahidul Islam, a nine-year-old boy, who helped Sinha on July 31 find the trail to climb a hill, and his grandfather Zahir Ahmed accompanied the officials as they visited the hill.
They also visited Baitun Nur mosque from where it was announced that there were robbers on the hill when Sinha was there.
Sinha used to make travel documentaries for a YouTube channel called Just Go. On the fateful night, he was returning to Cox's Bazar from Teknaf with Sefat.
His car was stopped at Shaplapur on Marine Drive road.
Police claimed they were about to search the vehicle when Sinha aimed his pistol at them, prompting the officers to open fire. They also claimed they seized drugs from the vehicle.
However, witnesses said Sinha stepped out of his car, put his hands over his head, and then a police officer shot him.
