( CNN ) -- A man filmed a group of girls attacking a 12-year-old girl in his neighbor 's garden , and told Providence , Rhode Island , police he thought it was a prank . Two of the girls have been charged with assault with a deadly weapon and conspiracy , and two others have been charged with simple assault and conspiracy , said Providence Police Sgt . Matthew Ryan . The 12-year-old suffered two black eyes , a bruised nose and bite marks on her hands . Holly Gingerella , the girl 's mother , said , `` My daughter is doing OK. She does n't look very good , but she 's a strong child . '' She said her daughter has a shunt in her brain to aid with a medical problem , but the shunt was not damaged in the assault . The man posted the video of the incident on YouTube , where he shows his face to the camera and describes the attack , `` Kids are ( expletive ) sitting outside for like 20 minutes saying , 'Do n't do this , do n't do that . You got ta keep going , you got ta keep fighting . ' They 're like planning it so they can just record it . '' While he speaks , girls can be heard shouting in the background . Ryan said additional cell phone video of the attack was turned in to police after it was confiscated at Woonsocket Middle School . The principal 's office was closed when CNN tried to contact the school . Ryan said the man is not being charged and is not involved in the case now that the video is no longer in his possession . Gingerella said she was `` horrified '' the man did n't try to stop her daughter 's attack . Gingerella said the leader of the girls invited her daughter to spend Friday night at her house and that all was normal between the girls . She said there had been no major incidents between them besides what she said were the usual ups and downs of a young school friendship . Gingerella described her daughter as someone who `` is very quiet . She likes to stay to herself . She tries to get people to like her . '' On Saturday afternoon , Gingerella said , the situation changed . `` My daughter said everything turned bad in about 10 minutes . She was attacked and they would n't stop . She got up and ran . Then they attacked her on the pavement . Nobody interfered . Not even the man who videoed it . '' Gingerella said the other girls posed as her daughter via text message , quickly canceling a request from her daughter to be picked up with a message saying , `` Can I please stay the night ? '' After the incident , Gingerella 's daughter started to walk home before being picked up by one of her friends , who she begged not to tell her mother about the incident because she was afraid of retribution , Gingerella said . When the girl got home , Gingerella said her daughter told her she was hit by a softball , but then began crying and explained what happened . Gingerella said there were no parents in the house at the time of the incident . The mother of the girl accused of leading the attack spoke to CNN affiliate WJAR and said , `` I love my daughter , too . But my daughter needs help . My daughter has done this too many times . She needs to be punished for this . '' Ryan said two of the girls had been turned in by their parents to police and charged as minors , while the other two are expected to be turned in soon . Parents of the other girls were not available for comment .
