Melaka police have arrested four Myanmar nationals over the death of a one-year-old boy. The child succumbed to physical injuries, and officers took the four into custody to assist with investigations. The arrests came as detectives worked to establish how the infant sustained wounds severe enough to kill him. Details about where the boy was found and who was caring for him have not been made public. A post-mortem is expected to confirm the cause of death, and investigators will use those results to decide on the next moves. Members of the public with any information about the case have been urged to contact the authorities. Charges will hinge on what the inquiry turns up, and the four remain in custody for now.
