Sick act: A 14-year-old girl has been arrested after posting a video on Facebook of a toddler performing a sex act on her

A teenage girl has been arrested after police uncovered a Facebook video of a toddler performing a sex act on her.

Police were "swamped with calls" after the 14-year-old shared the video with a male friend.

The teenager was arrested after one caller told South Carolina police who she was and where the incident took place.

"This is a devastating case where an innocent child is being abused and taken advantage of by someone whom the child should have been able to trust," Orangeburg Sheriff Leroy Ravenell told ABC News4.

"Parents we are calling on you to police your children - inspect their phones and social media accounts to see who they are talking to and what they are sharing. If you are paying for the phone service, you need to be checking behind your kids."

The 14-year-old was arrested for criminal sexual conduct with a minor and is being held at the Department of Juvenile Justice. Two other children in the home have been taken into custody by the Department of Social Services.
