The 11 News I-Team has obtained video of a violent scuffle between a school police officer and three middle school girls, and it brings into question whether the officer's use of force was justified.The girls had to be taken to a hospital, and their children were sent to alternative schools.Mobile users, tap here for videoA gash in a forehead and blood on a shirt is not what any parent expects to happen to a child, especially at school."She had six stitches. No, I'm sorry -- 10. Four on the inside and six on the outside," said Tashona Neals, the mother of 13-year-old Diamond. The girl's injuries came at the end of October inside Vanguard Collegiate Middle School in northeast Baltimore.What happened that day was captured on the school system's surveillance cameras. The altercation started when Diamond's cousin, Starr, had an encounter with the school police officer, who could be seen on the video looking up a stairway."Starr said they was changing classes," said Vanessa Ward, Starr's grandmother. "The officer was hollering at her and said, 'Little girl, get down here.' And so Starr said, 'My name is not little girl, it's Starr.' Starr came on down the steps, and Starr said that's when the officer grabbed her."The video shows the officer push Starr against a wall. Starr's sister, who was also a student at the school, said she heard there was a fight."So she goes over there thinking it's another child, and she gets over there, and it's an officer. She went over there to try to stop her," Ward said.Diamond arrived next in the video and appears to shove the officer, who then let go of Starr and gave chase, pulling a baton and using it. Diamond was hit at least twice it appeared, including the blow from the baton that put the gash in her head."I knew something had happened because I received a call from the paramedics," Neals said.Neals said she heard nothing from the school."So your daughter is in the office bleeding, and they don't call you?" I-Team lead investigative reporter Jayne Miller asked."No," Neals replied.All three girls were taken to a hospital: Diamond because of the head injury and her cousins because they were each sprayed with pepper spray. Miller reported that the same officer used the spray while another school employee tried to restrain the girls."The officer kind of comes from behind and reaches around and sprays them multiple times in the face with pepper spray. It's disgusting," said attorney Jared Jaskot, who represents the girls because he said they are the ones who've been punished.After the trip to the hospital the day of the incident, city police took the three girls to juvenile booking, where they were charged with assaulting the officer. The school system claimed the officer was kicked, scratched in the face and punched in the face and chest."I didn't see any of that on the video," Neals said.Prosecutors said they saw the video and dropped charges when the girls went to juvenile court."The state's attorney saw the tape and picture of my daughter, and we never even made it in to the courtroom. They came out and said it is being dismissed," Neals said.The three girls were also suspended and sent to alternative schools, the ones reserved for troubled kids, Miller reported. New city school system CEO Gregory Thornton upheld the suspensions, saying in a letter he'd reviewed that recommendation.The girls are currently fighting that decision with the help of Jaskot."He said that he reviewed their case and sustained the officer's findings. What he reviewed, I have no idea, and I can't wait to see," Jaskot told Miller.The police union president told Miller that the officer in the case has been reassigned to administrative duties. He said that happened just a few weeks ago after the girls' relatives filed a complaint, setting off an internal investigation. The union president said the officer was trying to make an arrest the day of the incident and, therefore, was justified in using her baton.A representative for the school system said the safety of students and staff is a top priority but could not comment on the altercation because of the ongoing investigation.
