"Parents are reminded to take this opportunity to reinforce safe behaviors with their children," police said in a news release." Tell your child to always walk with a friend, and to be aware of their surroundings. If a stranger approaches, be sure that your child knows what to do: yell or shout, run away and immediately tell an adult. Impress upon your child the importance of going straight to school and coming home immediately after dismissal, or leaving the bus stop."
