The father of the victim said his daughter was beaten in the Edison High School cafeteria after the girls who attacked her unsuccessfully tried to lure her into a bathroom.

"You can see in the video that they approach her in a premeditated way to hurt her," the father said. "She has a concussion, serious contusions to her head and face and it could have been much worse."

The video obtained by 5 EYEWITNESS NEWS was shot by another student on a cell phone and there are several videos of the attack on different social media sites.

"I met with the Edison principal and a Minneapolis police officer at the school Tuesday," said the father. "The principal admitted they were understaffed in the cafeteria that day with only four staff members on duty when they normally have six, and I find that unacceptable for the students' safety."

The girl's dad also said the principal told him the three girls who attacked his daughter would probably get a 10-day suspension from the school district and then return to Edison, but they will be separated from the school's general population for a short period of time.

"If we can save one kid in the future from experiencing something similar it is worth talking about it," the father said. "With the right type of punishment then we are headed in the right direction, but if this goes unnoticed it is going to happen again."

The Minneapolis School District declined an interview request, but issued the following statement:

"While MPS cannot confirm details of the incident at Edison due to data privacy laws, we were aware of the situation and staff worked quickly to resolve it. The safety of our students is our highest priority. Fighting is not tolerated at Edison, and we follow the MPS behavior policy for all incidents involving fighting. Unfortunately, in an age of instant social media, there will be times when we cannot reach families as quickly as we would like. Our first concern has to be with the immediate needs for safety and security. That was our goal in this situation. Again, we are limited from providing full and accurate details in order to protect student privacy, and we are focused on restoring a positive and safe learning environment at Edison."

Minneapolis police told 5 EYEWITNESS NEWS no arrests have been made, but investigators are reviewing the video and they are interviewing witnesses and will probably send the case to the Hennepin County Attorney's Office for review.
