In the beginning of August 1998, unionisable staff in the banking industry went on strike over a salary dispute, resulting in long queues inside and outside banking halls. By August 7, the industrial dispute was still unresolved, forcing management to take up frontline services to calm customers who were getting restless.
At about 10 o’clock, the prevailing uneasy calm was interrupted by sounds of gunshots coming from the direction of the US Embassy. As panicked customers queuing outside surged into the bank, the gunshots were replaced by the sound of an exploding grenade followed by a deafening boom that left those standing in the banking hall reeling in their heels.
