10:37 AM PT -- A rep for Quando tells TMZ ... "Quando was present during a shooting yesterday evening which resulted in the untimely death of another young man's life."
The rep continued ... "He himself didn't sustain any injuries during the shooting and is safe. We ask that his privacy is respected at this time."
Quando Rondo got caught in the middle of a deadly shooting in broad daylight in L.A. on Friday ... triggering a freak-out from the rapper.
Videos circulating online show Quando CLEARLY upset while talking to a police officer in West Hollywood right after the bloodshed. In the videos, Quando appears very animated, flailing his arms and stumbling backward.
At one point, Quando sees the police drag a body out of a black Escalade and he promptly walks away, screaming in agony.
A rep for Quando tells us the rapper is "OK," but then clammed up on us.
Law enforcement tells TMZ ... several gunmen drove to a gas station in Beverly Grove and opened fire, hitting a young man.
His friends loaded him into the black SUV and drove about a mile to West Hollywood, where they were stopped by police officers responding to the shooting scene. This was where the videos of Quando were shot and it appears he's just a witness.
Cops gave CPR to the victim, who was breathing, but not conscious. An ambulance rushed the victim to the hospital, where he died.
