A video from inside Oxford High School during a shooting on Tuesday shows students evacuating a classroom through a window after the suspected shooter appears to try to trick them into opening the door by pretending to be a sheriff. 

The video, taken by a student who shared it with his father, was then shared with Fox Detroit. CNN's Anderson Cooper also verified the video, attributing it to Mark Kluska.

"Sheriff's office. It's safe to come out," an unknown voice says from behind the door. 

A student responds with "We're not willing to take that risk right now."

"I can't hear you," the unknown individual responds. 

A student says: "We're not taking that risk right now," to which the individual responds with "Okay come to the door... bro." 

The students then turn to each other, suspicious that the person claiming to be from the sheriff's department said "bro." "He said 'bro' red flag," a student says.

A few seconds later someone whispers 'window' and they begin climbing out, then run across a walkway where a sheriff deputy opens a door, letting them into another part of the building. 

During a press conference, Oakland County Undersheriff Mike McCabe said police responded to the shooting at the high school at around 12:50 p.m.

Three students: a 16-year-old male, a 14-year-old female, and a 17-year-old female were killed in the shooting, police said, adding that there were multiple people injured, including a teacher. 

One suspect, a 15-year-old sophomore, was taken into custody, police said. 

Insider has reached out to the Oakland County Sheriff's office for additional verification on the video.
