Former 1970s radical Sara Jane Olson, who lived as a fugitive in Minnesota, went back to prison Saturday after her short-lived release on parole last week. According to the corrections officials, she has to serve one more year, as they miscalculated the date of her release.

“The department is sensitive to the impact such an error has had on all involved in this case and sincerely regrets the mistake,” the chief deputy secretary for the California Department of Corrections, Scott Kernan declared at a news conference quoted by the Associated Press.

61-year-old Olson was arrested Saturday and imprisoned in Corona, nearby Los Angeles. She will be taken to the same prison she walked out Monday, the Central Women's Facility in Chowchilla and she will not be released until March 17, 2009. Her attorney, Shawn Chapman Holley, was outraged by the action and declared she might go on with a new hearing in front of the judge who first sentenced Olson, as her client is now being “illegally imprisoned.”

“As far as we're concerned they're bowing to political pressure and they are wrong,” Holley said. “It's like they make up all new rules when it comes to her. It's like we are in some kind of fascist state.”

The Los Angeles Police Protective League welcomed Olson’s return in prison, saying: “Parole shouldn’t even be an option for terrorists who are convicted of murdering innocent bystanders and attempting to murder police officers…Anyone who tries to kill police officers should get significant jail time and serve their full sentence.”

Olson was charged in 1975 with attempting to bomb police cars with the Symbionese Liberation Army (SLA), a group that gained notoriety after they kidnapped newspaper heiress Patty Hearst.
