Two recent cases involving teens being lured into robberies through social media have prompted a closer look at how the schemes work - and what parents can do to keep their kids safe.

"Any application or social or gaming platform that you can message on can be a way to exploit children," said special agent Smith of the FBI.

In one case, Universal City police said Alyssa Victoria Canul, 17, was arrested after allegedly using dating sites to lure young men before robbing and assaulting them.
