Tamara Marion, 24, of Memphis has been arrested after videos shared on social media showed her abusing a four-year-old boy by performing a sex act on him, police said. A second video is said to show the child attempting to perform an act on Marion

Police were made aware of the videos on Monday when they received a tip that the clips were being shared online, WREG reported.

One video reportedly showed a woman identified by authorities as Marion pushing the boy to the floor, removing his pants and placing his genitals in her mouth.

The second video showed the boy attempting to perform a different act on the same woman, police said.

Information about the relationship between Marion and the child has not been released.

It's not known at this time where another person recorded the videos or whether the woman who is said to be Marion acted alone.

Police have not revealed whether they are searching for any additional suspects related to abuse captured on camera.

Marion remains in custody at this time, booked on multiple charges of sexual exploitation of a minor and rape of a child.

She was recently arrested in February, and threatened to kill another woman in front of law enforcement while at court related to a vandalism charge, WREG reported.

She was charged at that time with two counts of violating an order of protection and two counts of retaliation for past action (threats of bodily harm), related to threats made to two women who are said to be the victims in the vandalism case.

Authorities said Marion became 'belligerent' and 'loud' at the time, and stated, 'she put these false charges on me. When I get out, I’m going to come back here and kill her.'
