BURIED under several floors of concrete in an undisclosed location is a cold room accessible only after many layers of security checks.
Wired up with screens, computers and telephones, this is where all 999 emergency calls are routed to. And it is where the police get wind of any outbreak of misdeeds across the island.

It was after 8am and she had started her shift just moments before. She threw on a jacket to beat the room's Arctic temperature, positioned a black set of Sennheiser headphones on her head and gave the volume on the headset a tweak.
She was ready for action.
Before her was a computer monitor which displayed information on the calls received. Her fingers were poised over a keyboard, ready to enter information for relay to the various police units and the Singapore Civil Defence Force.

She repeated her greeting a few more times and then hung up on the nuisance caller.
