Police say a teenage boy was stabbed several times during a robbery. 

The robbery, caught on camera, happened at the corner of Atlantic and Euclid avenues. Police say it happened a little before 6 a.m. and that a 15-year-old was stabbed in the neck and the back. 

The video shows at least three people, including the victim, who were involved in the incident. The video shows two people standing together in the middle of the block when a third person approaches them, and an altercation starts.

"There was a lot of commotion and I heard one kid was like 'stop, stop, what are you doing'...and then they ran up to the corner...and I saw the kid fall to the floor,” a witness tells News 12. 

The 15-year-old victim was sent to the hospital with serious injuries and is in critical condition. 

Police say they have surveillance video that shows someone fleeing the scene.
