Sheriff's officials say three California correctional deputies have been arrested on suspicion of murder in the death of an inmate at a county jail.

Santa Clara County Sheriff's spokesman Sgt. James Jensen said the deputies were in custody on Thursday.

Jensen declined to release additional details, including the inmate's and deputies' names. He said the sheriff's office planned to hold a news conference later in the day.

Thirty-one-year-old Michael Tyree died last week at the jail. The San Jose Mercury News reports (http://bayareane.ws/1O0mA5i) that he had pleaded no contest to petty theft.
