As the royals were leaving the center, they were met with anguished cries for help from a crowd of about 40 people.
One man held a poster of a missing person, and shouted that he wanted to speak to the queen about lost children. The queen waved to the crowd, and then hesitated before getting into her car.
Some continued to shout in desperation prompting William to respond: "I'll come back, I'll come back."
