MILWAUKEE, Wis. (WRN) - Seven juveniles and an adult have been arrested for their part in a fight at Milwaukee's Vincent High School. Three Milwaukee police officers and a school safety assistant were attacked. The fight broke out Friday afternoon about 4 p.m. in the school parking lot. One officer was hit in the face, another kicked in the leg and the third punched in the head. A spokesperson for Milwaukee Public Schools says the fight was started by a group of outsiders who came to Vincent and attacked a student. Last month students at Vincent were told they would have to go through a metal detector to enter the school, due to widespread fighting there.
