A Sacramento inmate who was released this week as part of a state plan to reduce the prison population is back in jail again.

After being released Monday night, Sacramento police say 22-year-old Kevin Peterson was arrested a little after noon Tuesday on suspicion of attempted rape.

Police Sgt. Norm Leong says Peterson is being held without bail after allegedly trying to rape a female counselor he was meeting with and holding her captive.

Peterson had been released 16 days early from the Sacramento County Jail after serving two months of a four-month sentence for violating probation.

He had previously served a one-year sentence for felony assault.

Under a law signed by Gov. Arnold Schwarzenegger jails are now required to release inmates for good behavior after serving half their sentence.
