They always kept the windows of their flat closed, according to some neighbours.

Additional Deputy Commissioner of Counter Terrorism Unit Sanwar Hossain said Tamim and his two aides had no plan to surrender and were planning to destroy key evidence.

"We requested the militants to surrender several times between 6:30am and 6:45am. But, they didn't respond," he said.

"In the meantime, they destroyed evidence by setting fire to one of the rooms. They also broke laptops and mobile phones. This prompted us to launch the operation around 8:45am."

He also said police wanted to detain the chief alive as a lot of information could be gathered from him.

"It was our prime objective to arrest them alive," Sanwar said.
