Police say a member of the Kennedy family was arrested after a bar fight in the tony resort town of Aspen.

Police say 22-year-old John Conor Kennedy, who once dated pop superstar Taylor Swift, was charged with disorderly conduct in the Thursday morning scuffle. Kennedy is the oldest son of Robert Kennedy Jr., an environmental activist, and the grandson of Robert Kennedy.

Police say Kennedy and another man were fighting in the street and rolling around on the ground when officers tried to separate them. Officers reported seeing Kennedy punch the man in the head four or five times.

Kennedy allegedly struggled against an officer who was trying to restrain him before they both fell into a snowbank.

It was unclear if Kennedy has an attorney who could comment on his behalf. A court appearance is set for Feb. 22.
