Former Redskins wide receiver Zion B. McKinny has been suspended with pay as chief of security at Chantilly High School in Fairfax County because of an accusation that he assaulted a student, Principal George Keim said yesterday.

Keim said the incident occurred last Wednesday after the student refused to produce a hallway pass at McKinny's request and cursed him. McKinny allegedly grabbed the student's arm and carried him upstairs to the assistant principal's office, Keim said.

The student did not require medical treatment. His mother complained to police and school authorities after the incident, although no police charge was filed, said police spokesman Warren Carmichael.

McKinny, 29, who has an unlisted telephone in Prince William County, could not be reached for comment.

"No adult should rough up a student, and he knows that," Keim said. "He was confronted with a situation where he thought restraint was required. That's the reason it's being investigated. It's questionable."

Keim said McKinny has worked at Chantilly for three years. He said McKinny has been investigated before for alleged assaults on students, but the allegations were dismissed or were not serious enough to cost him his job.

McKinny, who lettered for four years at the University of South Carolina, joined the Redskins as a free agent in 1980 and played for one season, according to the Redskins public relations office.
