Two Ansar members posted as security guards at the Radhaganj Bazar branch of Agrani Bank in Raipura upazila of Narsingdi were found dead inside the bank on Wednesday morning.
The deceased were Tauhidul Alam, 24, of Faridpur, and Ranju Mia, 40, of Tangail.
Branch Manager Fakhrul Islam said the cleaning staff of the bank came in the morning and found the gate blocked from the inside. They did not get any response after knocking for a long time.
When the bank authorities were informed, they called the police. Later, police broke down the door and recovered the bodies of the two security guards around 9:30am.
Police sent the bodies to the Narsingdi Sadar Hospital morgue for autopsy, he said.
No money was stolen from the volt, he added.
Azizul Islam, officer-in-charge (OC) of Raipura police station, said the two security guards may have died from food poisoning. “Whether there is any other reason for their death can be confirmed after receiving the autopsy report,” he said.
