The actor was arrested earlier this month (Oct15) after he was accused of attacking a woman with a knife during an altercation in Los Angeles in August (15), when the unidentified female had reportedly tried to stop Jackson from taking her boyfriend's car.
He was slapped with felony count of assault with a deadly weapon and was held on bond.
Jackson, who spent his 35th birthday on 16 October (15) in jail, made bail on Tuesday (27Oct15) and his lawyer tells ETonline.com he headed straight to a treatment centre for voluntary help.
The star, who has pleaded not guilty to the crime, is due back in court on 20 November (15). If convicted, he faces up to seven years in prison.
The news emerges months after his last arrest in April (15), when he was also accused of stabbing a man and fleeing the scene. He was also charged with assault with a deadly weapon for that incident, in which Jackson insisted had been the victim of an attempted robbery.
The troubled star has previously struggled with substance abuse and featured as a patient on Celebrity Rehab With Dr. Drew in 2011.
