(CNN) -- A young man and a teenager were arrested Sunday in connection with a video posted to YouTube showing an attack on a homeless man in New Jersey, police said.
Wall Township police identified Taylor Giresi, 20, as the assailant in the video, and the homeless man as David Ivins. They did not identify the 17-year-old -- a juvenile -- who was operating the camera.
Giresi has been charged with aggravated assault and conspiracy to commit assault. He's being held at Monmouth County Correctional Institution in lieu of $60,000 bail, police said in a statement. The 17-year-old was charged with conspiracy to commit assault. He was released to the custody of a parent pending a court appearance, police said.
The video, which has since been pulled from the video-sharing site, "showed that the subjects involved took advantage of the victim's unfortunate circumstance and targeted him on two separate occasions due to his financially destitute situation," police said in a statement.
In one clip, a young man approaches Ivins as he is sitting and kicks him in the head. The young man and the person shooting the video laugh.
Later, as Ivins walks away from the men with his bicycle, the assailant pushes him to the ground from behind. Ivins' nose is bloodied when he stands up.
In an apparent gesture of apology, the young man then hugs Ivins, only to knee him in the stomach mid-hug.
Ivins collects himself after that blow and stands up again, but soon after the assailant delivers a jumping kick to his side, which sends him crashing into a bush.
The video's shooter wishes Ivins a "Merry Christmas" and "Happy Hanukkah" as they part ways.
"It was overactive, aggressive for no reason other than for their amusement," Detective William Bono of the Wall Township Police Department told CNN affiliate WCBS.
Giresi's mother told WCBS that his father died a few weeks ago. "It's wrong what he did. I can't believe my son would do something like that," she said.
In the wake of public outrage over the video, the Wall Township Police Department has set up a donation fund on Ivins' behalf. Money donated to the fund "will be used to provide the victim with food, clothing, shelter and other necessities he may need," the department said in a statement.
