BROOKLYN - Police officials say security footage shows a man leaning into the car of an off-duty officer before being fatally shot.

According to police, Officer Wayne Isaac was in his personal vehicle Monday morning when he was involved in a traffic dispute with 37-year-old Delrawn Small.

They say Small got out of his car at a red light and began punching the officer through an open window.

The officer responded by shooting Small.

Police say a passenger in Small's car became enraged after he thought the officer cut him off.
