Police in Philadelphia are seeking the public's help in identifying a woman seen in a viral video kicking a little boy on the playground and threatening to make him infertile.

The disturbing incident happened at Tacony Park in Philadelphia. A video of a woman kicking and screaming at a young boy was caught on cellphone video by Kelly Jax and posted on Facebook earlier this week.

In the video, a little girl and boy appear to be fighting when the little boy kicks the girl in the stomach. An unidentified man separates the kids, saying 'stop kicking, no kicking y'all'.

The woman was seen in a video kicking the boy multiple times and screaming at him

As the man tries to keep the kids apart, a woman kicks the little boy hard in the butt multiple times.

'No kicking,' she yells, kicking the child a second time. 'You wanna kick? How you feel? You kicked her in the stomach, I'm gonna kick you in your f***ing nuts and you ain't gonna be able to have kids.'

As the woman yells the little boy tries to get away from her. The two adults and the two kids, who were joined by a third child, then leave the park.

Jax, who was at the park with her two young granddaughters, said she posted the video hoping someone recognizes the adults in the video.

'Any one recognize this woman,' she wrote. 'At first it looked like the kids were playing but she wanted her daughter to fight the boy.'

Jax told PhillyVoice that the unidentified woman initiated the incident when she told her daughter to 'get' the little boy.

'The daughter grabbed him in a headlock and they both fell to the ground. The boy didn't want to wrestle or fight her. The look his face said it all,' she said. 'The little girl was on top of him and the boy kept trying to get her off of him and let go of the headlock, he rolled her over to the right almost hitting his head on the metal pole. He used his feel to push her off. ... That's why I started recording'.

She said she did not intervene because she had her granddaughters with her and was afraid the woman would turn violent. Jax said another woman followed the lady to a nearby store and confronted her.

The woman from the video reportedly told the woman who pursued that the little boy was her foster son.

The Philadelphia Police Department posted on its Facebook page that they are looking for the man and woman from the video. If anyone has information on their whereabouts they are asked to call (215) 686-8477 or click here to submit an anonymous tip.
