SINGAPORE: A siren shrieked across the water as a black dinghy darted across the waves. Hot on its heels, a Police Coast Guard (PCG) boat vaulted over the choppy tide near East Coast beach to catch up with the “illegal vessel”.   In a matter of seconds, another PCG boat arrived in a spray of mist, part of a tag team to capture the rogue boat as part of a demonstration for the media.
