NEW YORK, Aug 6 (Reuters) - A Citigroup ( C/PN ) executive

who joined the bank from Bank of America ( BAC ) in April is

leaving Citi, one source with knowledge of the matter said on

Tuesday.

Don Plaus, named head of North America for Citi's private

bank, said last week he was leaving for personal reasons, the

source added, requesting anonymity to discuss personnel matters.

Barron's was the first to report his exit. Plaus had joined

Citi after retiring from a three-decade career at Bank of

America's ( BAC ) Merrill Lynch. Citigroup ( C/PN ) declined to comment and Plaus

did not reply to requests for comment.

Plaus was hired by Andy Sieg, Citi's new head of wealth

since last year. They had worked together at Bank of America ( BAC ).

Wealth management is a key growth area in CEO Jane Fraser's

plan for improving Citigroup ( C/PN ) profitability.
