Chattooga County Sheriff Mark Schrader is joining law enforcement agencies across the country in warning parents about a violent online extremist network known as “764,” which authorities say targets minors through social media, gaming platforms, and private chat features.

Authorities say the group and similar networks use manipulation, sextortion, blackmail, and threats to pressure children into sharing explicit material, harming themselves, or hurting others.

Officials say parents should watch for warning signs such as sudden secrecy with phones or computers, multiple online accounts, staying up late to chat with unknown individuals, and fear or panic when a parent asks to see a device.

Law enforcement recommends keeping computers and gaming systems in common areas, setting device time limits, reviewing friends lists and messaging apps, and maintaining open conversations with children about online dangers. Parents and guardians are encouraged to reassure children that they can speak up without fear if something feels wrong online.

Anyone who believes a child may be in immediate danger should call 911. Suspected online exploitation should also be reported to the proper authorities.
