According to the publication, Conor Kennedy was outside the Bootsy Bellows Nightclub when a group of four men started calling his friend an antigay slur.

Kennedy asked them to stop and apologize, and one of them did. Later on, however, two of the men continued to throw slurs at his friend and a fight ensued.

Robert Kennedy claims Conor Kennedy’s friend was not physically involved in the fight. Conor Kennedy also did not throw the first punch, said Robert Kennedy.

“We are aware of some of those allegations and we are following up on them this evening,” Aspen Assistant Police Chief Bill Linn told the newspaper. “At the moment, there have been no allegations of additional crimes given by witnesses or those involved in the incident.”

Conor Kennedy is the great nephew of former U.S. President John F. Kennedy and grandson of late New York Senator and U.S. Attorney General Robert F. Kennedy.
