Sept 10 (Reuters) - Citigroup ( C/PN ) said on Tuesday its

chief accounting officer Johnbull Okpara will be stepping down

from his position at the bank.

The bank announced that insider Robert Walsh would assume

the role of interim chief accounting officer as it conducts a

search for a permanent replacement.

"Johnbull will stay at Citi to drive the third quarter

earnings process and then will advise as needed through the

filing of the 10Q (quarterly filing with regulators) to ensure a

seamless transition," Citigroup CFO Mark Mason said in a memo.

The bank did not immediately respond to a request for

comment beyond the memo.
