A bizarre video posted to social media claims to show a woman who has been a missing person since she was three years old.

Uploaded to TikTok on Wednesday, the video is captioned "Diamond Bradley missing for 21 years" and claims to show the long-lost child, now grown up.

"This is Diamond Bradley," the person holding the smartphone says, focusing on Black woman with her. "Can I see your scar?" 

The woman then appears to lean forward to show a scar with a nervous laugh. In the video, the group of women is recording themselves speaking next to a parked Harris County, Texas, law enforcement vehicle.
