Byron Vann arrested and charged with murder.

 Police in Wahpeton are investigating after a man was attacked with a bayonet.
Police Chief Scott Thorsteinson says 31-year-old Byron Vann of Henryetta, Oklahoma, has been charged with attempted murder.
KFGO-AM reports that Vann was arrested Friday night after he returned to the scene while officers were still there.
Thorsteinson says the victim, a 30-year-old Fargo man, underwent surgery at St. Francis Medical Center in Breckenridge to repair "two significant neck wounds." He was released from the hospital the following day.
Vann was in the Richland County jail. A court official said no attorney had yet been appointed for him Monday.
