MESA, Ariz. (AP) -- Authorities say a Mesa father has fatally shot a man who was beating up his son outside his family's home.

Mesa police say a fight broke out in the front yard of the home around 5:30 a.m. Monday.

Police say the homeowner came out of the house to see his son being attacked and fired a weapon at the person beating up his son.

Others involved took the victim to a hospital, where he was pronounced dead.

The names of the people involved haven't been released, but police say the son knew the attacker.

Police say it's still unclear what led to the fight and if any charges will be filed in the case pending an investigation.
