ARLINGTON, Texas (AP) Police say a North Texas man has been arrested after his neighbor was fatally shot while the two men argued.

Arlington police are trying to determine what sparked Tuesday night's killing. The name of the victim wasn't immediately released.

Police say 66-year-old Franklin Hudson of Arlington was jailed Wednesday on a murder charge. Bond has been set at $500,000. Arlington City Jail records did not list an attorney for Hudson, who police say fired at witnesses before being arrested.

No bystanders were hurt.
