Dhaka: Investigation agencies are yet to confirm about the involvement of ex-North South University teacher Abul Hasnat Rezaul Karim and Toronto University student Tahmid Hasib Khan in Gulshan café attack as the probe in this regard is yet to complete, said police.

‘They’re being quizzed on remand, and it’ll be known after investigation whether the two suspects had any involvement in the attack,’ additional commissioner of the Dhaka Metropolitan Police (DMP) and chief of Counter Terrorism and Transitional Crime (CTTC) unit Monirul Islam told reporters at the DMP Headquarters on Sunday, reports UNB.

On Thursday, a court placed Hasnat and Tahmid, arrested from the city in connection with the Gulshan terror attack, on police custody for eight days each.

‘We’ve been examining the photographs collected after the Gulshan attack and also scrutinising the body language of the two suspects to understand whether they fell victim to the situation or in what circumstances the firearm Tahmid was holding,’ said Monirul.

Hasnat and Tahmid were arrested under section 54 of the CrPc. If their involvement in the Gulshan attack is found they will be shown arrested in the case filed over the terror attack, said the CTTC unit chief.

‘We’ve got many information , including who were involved and played the role in the attack as well as names of the possible arms suppliers and trainers involved in giving training to the attackers ,’ he said.

‘It is not the time to disclose everything. Let the investigation to proceed further and we’ll specifically disclose everything after arresting some suspects in connection with the incident,’ he said.

Replying to a question, the CTTC unit chief said they are yet to arrest anyone in connection with the Gulshan attack.

Besides, he urged the journalists to refrain from reporting on the issue without talking to those involved in the investigation.

Twenty hostages, including 17 foreign nationals, were killed by militants, while five militants and one suspected associate of the attackers were killed during a commando operation inside the café on 2 July.
