Geoffrey Kelly, 53, was arrested for attempted murder.

REDDING, Calif. -- The father of an 8-year-old boy who police found bloodied and beaten with a baseball bat is under arrest on suspicion of attempted murder.

Redding police say 53-year-old Geoffrey Kelly flew into a rage on Thursday morning and struck his son multiple times with an aluminum baseball bat.

Police Lt. Tracy Beaupre told the Record Searchlight the boy is in critical condition with life threatening injuries.

The boy's mother told police she was stirred from sleep by the attack, and found Kelly standing near the boy's bed.

Police say Kelly has a criminal history, and in February he was arrested after threatening officers with a hammer and stabbing himself with a knife.

Kelly is being held in Shasta County jail on $500,000 bail.
