Glen Campbell pleaded guilty on Monday (May 10) to charges of extreme driving under the influence and leaving the scene of an accident. He was sentenced to 10 days in jail but will be eligible for work furlough after 48 hours. He will also serve 75 hours of community service. Following his arrest near his Phoenix home in November 2003, Campbell allegedly kneed a police officer in the groin while in custody, but a charge of aggravated assault was dropped. Extreme DUI applies to a blood-alcohol content of 0.15 or higher. Campbell's breath tests at the time of his arrest indicated a 0.20 blood alcohol level, according to police.
