I had a friend who put a very young baby down onto a display bed in a Wing On store. The baby was around 3 months old, and the mother put it there as stood close by while speaking to a sales person. According to her, she turned her head, to see a mainlander (around 50 years old) walking off, very briskly, holding the baby. She chased after her, and when confronted, the lady said she was "taking the baby to a security guard". She then very quickly exited the store after that. Who knows what might haave happened had she not been stopped.
