OKLAHOMA CITY - An Oklahoma City man dies following a fight at an apartment complex.
The victim passed away just hours after defending himself from a violent assault.
The suspect remains behind bars at the county jail but he's not charged with murder because police aren't sure what caused the victim to pass away.
The death was not due to injuries suffered in the fight.
It all happened at the Andrews Square apartments on S. Harvey.
Witnesses said one resident, 43-year-old Rocky Broughton, began threatening another resident with a BB gun and a knife.
That's when the victim, 60-year-old Phillip Scales, hit his attacker with a board and then held him down until police arrived.
"What makes this story different is the victim died the same day from unknown causes," OKC Police Master Sgt. Gary Knight said.
Police said the victim complained of chest pains but repeatedly refused treatment by paramedics only to die of an apparent heart attack hours later.
"At this time it's unclear what killed him," Knight said. "It doesn't appear he was injured enough to cause his death. Nobody thought he was in immediate peril at the time."
The state medical examiner's office will determine the exact cause of death.
The suspect is being held on a charge of assault and battery with a dangerous weapon.
That charges could be amended because of the victim's death.
