A video shows a teen being attacked by a large group of people at Luna Park in Coney Island. 

The incident happened Sunday at Luna Park amid false reports of shots being fired which sent crowds of people running and prompted a large police response.

The 16-year-old was transported to the hospital in critical condition with a partially collapsed lung.

Investigators say a 26-year-old man also suffered cuts to the face.

No arrests have been made and police are classifying the video as a gang related assault.
