It seems like Blueface's street code is preventing law enforcement from putting together a case against his alleged assailant.
The L.A. County District Attorney's office tells TMZ Hip Hop ... the case has been rejected, for now, due to Blueface's lack of cooperation with the investigation. The video doesn't clearly show everything necessary to bring a criminal case, so, we're told investigators needed cooperation from witnesses to move forward.
According to docs, Blueface refused to answer any of the responding officer's questions, refused to provide his ID and even rejected medical aid ... though he quickly posted his bloody injury on social media, assuring fans he was good.
As we previously told you, Brandon Henrysnell had turned himself in on August 24, and was booked for felony assault with a deadly weapon.
But, the case won't go any further ... as authorities reviewed the footage, and while it clearly shows an altercation, it's missing the key moment Brandon allegedly stabbed Blueface.
Blueface had been training in a gym at the time of the attack and an urgent call was made to rush medics to the scene. Turns out that 911 call is as much cooperation as law enforcement's getting in this case.
