Brad Renfro isn't such an "Apt Pupil" after all.

The 23-year-old actor was sentenced to 10 days in jail on Wednesday, March 8 when he pleaded guilty to driving under the influence, and thus violating his probation. He was immediately taken into custody and sent to prison.

Renfro already has two prior DUIs. For the plea agreement for this current one, the Los Angeles Metropolitan Court judge ordered the 10-day jail sentence, that the actor attend an alcohol program as well as a "hospital and morgue" program, reports TMZ.com.

The last can either serve as a condition of probation or as an alternative sentence. In the program, the offender observes an evening in the emergency room of a local trauma hospital and then visits the Department of Coroner to witness an autopsy procedure (usually a substance abuse-related traffic fatality).

In return for pleading guilty to DUI, other charges, including driving with a suspended license, were dismissed.

Just two days earlier, on Monday, March 6, Renfro was in court on separate heroin charges, in which he was ordered to attend a rehab program. The sentence stems from a December arrest in which he admits to trying to buy heroin in a drug sting in downtown LA from undercover cops.

He has a history of run-ins with the law including: a 1998 arrest on cocaine and marijuana charges for which he struck a plea bargain, probation for attempted theft of a yacht in 2000, an arrest for underage drinking a year later and a 2002 bust for public intoxication and driving without a license.

Renfro first broke out in 1994's "The Client" and went on to lead roles in "Apt Pupil," "Bully" and "Telling Lies in America." He was most recently seen in a supporting part in "The Jacket."
