Blueface Stabbing 911 Call, Gym Owner Loses Patience with Operator Blueface 911 Call 'He Stabbed My Client' ... Get Here Pronto!!! Exclusive 202 9/16/2023 12:15 AM PT

Moments after Blueface got stabbed in a boxing gym, his trainer dialed 911 and the call got pretty intense ... with the operator trying to get details of the attack, as the trainer tried to get medics to save Blue.

TMZ Hip Hop obtained audio of the 911 call that launched paramedics to the bloody scene on August 23 at the Kaminsky Boxing Gym in L.A.'s San Fernando Valley.

On the call, the trainer -- who also owns the gym -- tells the operator a random guy came in and "stabbed my client" ... and then the miscommunication begins.

Seems the gym owner couldn't really hear the operator's questions about whether the assailant was still there -- and the gym owner quickly grew frustrated as he urged the operator to send help right away for Blueface ... who was bleeding from his leg wound.
