Gallaudet University has suspended a fraternity for the third time in three years as the school investigates a student's claim that he was hazed and injured while pledging.

Howard Busby, vice president foracademic and student support services, said he ordered Kappa Gamma to cease all activities Friday, two days after a student filed a complaint alleging that the fraternity had violated the school's new anti-hazing policy during pledge initiation last month.

Gallaudet requires all student organizations to sign hazing-compliance forms promising not to make pledges participate in an "activity that adversely affects the mental or physical health or safety of the student."

Busby, who spoke through a sign-language interpreter, said he is interviewing the students who were involved with the initiation activities and will decide late this month whether to ban the fraternity permanently. "The charges are sufficient to warrant a suspension of their activities," he said.

In the complaint, Kevin Clark alleged that he passed out and fell and hit his head after Kappa Gamma members forced him to stand for a long time, Busby said. Clark told school officials that he had been to the hospital because of his injury, Busby said.

Busby said he is trying to determine whether other students were hurt in the initiation.

Clark did not return messages left for him on the school computer system or at the student message center.

Leaders of Kappa Gamma, which was established in 1901 and is not affiliated with any national Greek organization, also did not return messages left at the student message center and in the computer system. The fraternity has about 30 student members and about 1,500 alumni, university spokeswoman Muriel Strassler said.

The fraternity was suspended from April to November 1992 after two students filed a complaint charging the fraternity with racial harassment and with excluding African Americans. One of the students, senior Ritchie Bryant, responded in writing to written questions in an interview after the suspension was lifted. He said fraternity members used a racial epithet in computer messages and in signed communication.

University President I. King Jordan lifted the suspension in November and wrote in an all-campus memorandum that "individuals {who belonged to the fraternity} behaved in ways that demonstrate insensitivity at best and racial prejudice at worst, {but} I find no such evidence that the fraternity promoted such behaviors."

The fraternity was allowed to resume its activities if it cosponsored three campus events with the Black Deaf Student Union and submitted to monitoring by Busby.

"I am outraged at the way King Jordan handled the case. . . . It is as if nothing happened," Bryant said at the time.

Kappa Gamma also was suspended for hazing violations from November 1991 to April 1992, Busby said. That suspension resulted when Busby was given a photograph of the bruised bottom of a pledge who said he had been paddled during initiation.
