BOISE, Idaho (AP) — An Idaho inmate has been charged with felony aggravated assault in connection with an attack on another prisoner on New Year's Eve. Rick Lee Sykes, 34, allegedly punched another inmate in the head about a dozen times, knocking him unconscious.

The Idaho Statesman reports that Sykes was moved from prison to the Ada County Jail to be charged with the crime on Wednesday. Prison officials say the victim needed stitches to his nose, eyebrows and lips. If convicted, Sykes could face up to five years in prison. He's currently serving a sentence for a March 2008 attempted strangulation charge, and a separate October 2008 aggravated assault charge.
