On April 10, the Ariful wearing the jersey of the Bangladesh cricket team entered the booth around 5:15am and attempt to break the ATM but the security guard Hasan Mahmud, 55, tried to prevent him for the doing that.

He stabbed the guard, leaving him dead on the spot and the next morning police recovered the body.

Ariful tried 10 to 12 minutes to break open the ATM but failed to take out the cash. Later, he left the booth and immediately.

The accused in primary interrogation confessed his involvement in killing the guard, the DB chief said.
