The police has investigated a loud sound at Sentosa Cove and did not find anything incriminating. Earlier, a resident there complained that they heard a loud sound and felt insecure about it. From their investigations, the sound was probably due to a demolition exercise carried out at the nearby Southern Islands. The exercise is part of a series of tests that will be conducted from mid to end May. Good that it's no big deal, but how come they never inform residents one?
