Williams said her 13-year-old son was one of four teenage boys, all related, who wanted to take photographs of Harrison and asked him for autographs. Williams said although she was nearby, she did not witness the incident.
However, she said, her son told her Harrison was on a cell phone and told them to wait. He later went on the cell phone again and two men showed up, Williams said. She said her son told her one of the men punched a 15-year-old boy in the jaw. The youth was taken to the hospital, she said.
Williams said her son told her Harrison also shoved one of the boys and placed a "chokehold" on him.
"On behalf of our family and our sons, we are willing to pursue this matter to the fullest," Williams said. "We would like the authorities in Hawai'i to cooperate and not give this guy special treatment because he's a high-profile football player."
Honolulu lawyer Michael Green, attorney for the youths' families, said Pro Bowl players are idolized by youngsters and the incident should not be tolerated.
"It can't be ignored," he said. "They're just asking that justice be done."
