The attacker, Ricky Rose-Mooring, 25, stabbed the owner of St James nightclub in Geelong and a doorman after he was kicked out. In the CCTV footage the shirtless Rose-Mooring was shown stabbing the security guard who didn't realised he was injured.
Both of the victims were taken to hospital in a serious condition and required surgery. The attacker was diagnosed with attention deficit hyperactivity disorder (ADHD).
The owner said he has since struggled with panic attacks and endured significant financial losses as a result of decreased patronage over safety concerns.
Rose-Mooring was remanded in custody for sentencing on March 29.
