The New York Yankees filed a complaint with the Chicago Police Department over the actions of one of its officers.
The Chicago Sun-Times reports that the off-duty 9th District officer was working as extra security at U.S. Cellular Field during a four-game series between the White Sox and Yankees in May.
The officer apparently broke protocol, and asked Derek Jeter to sign several autographs for a police charity fundraiser.
It was witnessed by a Yankees' security guard, all of whom are former police officers.
Some are questioning if it was for charity at all.
Chicago Police Superintendent Garry McCarthy told the newspaper that the department's Internal Affairs Division is investigating the incident.
