(InvestigateTV) - Lurking on popular online games and social media are predators that officials with the FBI say are part of a network of extremists.

These cybercriminals are known for coercing their victims into self-harm and other acts, according to FBI special agent Heith Janke."Many of these actors are motivated by nihilistic violent extremism and what that generally means generally is they want to sow chaos and they want the destruction of our society," Janke said.

As authorities work to stop this threat, they say parents are the first line of defense for their children.
