LITTLE ROCK, Ark. (AP) -- An Oklahoma police officer who was in Arkansas for sniper training was punched in the nose during a bar fight and later died at a hospital.

Police say 25-year-old Elzie Cain got into a fight with 26-year-old Aaron Threlkeld at about 4 a.m. Sunday at the Electric Cowboy in Little Rock.

Cain hit his head on the floor and died at a hospital Sunday afternoon. Little Rock police spokesman Lt. Terry Hastings says Threlkeld was arrested for first-degree battery but said he expects the charge to be upgraded to first-degree murder.

Authorities didn't know Monday whether Threlkeld had an attorney. He was released Sunday on $10,000 bond.

Cain was in the Little Rock area for training as part of his duty with the Oklahoma National Guard.
