Scottie Pippen 911 -- Victim 'Knocked Unconscious' ... 'Suspect Fled'

Scottie Pippen fled the scene after knocking a fan unconscious outside a Malibu restaurant last month ... this according to the 911 tape obtained by TMZ.

During the call, an emergency responder communicates with 911 dispatch ... who says the victim was knocked out cold outside Nobu. The incident was described as an assault.

But the crazy part ... the dispatcher says the "suspect fled," leaving the victim unconscious in the parking lot. Pretty effed up.

As we reported, Pippen has accused the victim of calling him the n-word and spitting at him, which is why Pippen attacked. The victim has since denied the allegations, saying he just wanted a photo.
