NEW YORK -- A Brooklyn man was killed and his brother was arrested in a fight over a New York Yankees baseball cap, police said Friday.

Frank Ross, 49, who was confined to a wheelchair, was stabbed once in the torso Thursday night during the dispute outside his home in the Crown Heights section, police said. The man was pronounced dead an hour later at Kings County Hospital.

The victim's brother, Kenneth Ross, 44, was in police custody on charges of second-degree murder and assault, police said.

The dispute started when Kenneth Ross confronted his brother and accused him of stealing his baseball cap, police said. When Frank Ross denied it, his brother stabbed him, police said.

A 60-year-old neighbor also was stabbed in the stomach when he tried to intervene, authorities said. He was in critical condition at Kings County Hospital.

The neighbor was able to alert the brothers' sister, and she called police, who recovered a kitchen knife and a folding knife at the scene, authorities said.

Police said Kenneth Ross has a lengthy criminal record, including a murder conviction.
