Top uniformed FDNY chief accused of 'inappropriate behavior'

The top uniformed officer of the New York City Fire Department has been relieved of his duties amid an investigation into accusations of "inappropriate behavior."

FDNY Deputy Commissioner Frank Gribbon said Thursday Chief James Leonard, 59, has been placed on modified assignment.

Chief of Operations John Sudnik is now the acting chief of the department.

Leonard was only second in command to Fire Commissioner Daniel Nigro. He has been with the FDNY for nearly 40 years. He began his career as a firefighter in Brooklyn.

The NY Daily News reported earlier this week on allegations that Leonard was 'butting heads' with First Deputy Fire Commissioner Laura Kavanaugh. She is the top ranking female in the FDNY.

He has allegedly run into problems with other chiefs and FDNY staff due to his 'abrasive and aggressive manner,' added the Daily News.
