A 16-year-old student at Warren Fitzgerald High School was stabbed to death at the school Wednesday morning, according to Warren Police. The victim was reportedly stabbed twice in the chest.

Police say a 17-year-old girl is in custody for the stabbing death. Warren Police Commissioner William Dwyer said there is a male student who is also involved in the incident, and it’s possible that both the victim and the suspect had a relationship with the male student.

Authorities say a 16-year-old girl has died after being stabbed by another teenage girl during a fight inside a high school classroom in suburban Detroit.

Warren Police Commissioner William Dwyer says the girl was stabbed twice in the chest Wednesday morning at Fitzgerald High School and was pronounced dead about an hour later at a hospital. He says the 17-year-old suspect used a kitchen-style knife.

Dwyer says the students knew each other and suggested the dispute was over a male student. Police say the other girl was taken into custody at the scene.

The school was initially placed on lockdown but students have since been released.
