The chief executive of Dubai lender Emirates NBD's investment banking division is leaving the bank, three sources familiar with the matter said.

Suresh Kumar, who was a board member and named the head of Emirates NBD Capital in 2009, has worked with the bank for over 20 years and held senior management roles with Emirates Bank Group before its 2007 merger with National Bank of Dubai.

A spokesman for ENBD declined to comment on Sunday.

Last year, ENBD consolidated its investment banking and financial advisory businesses under its Emirates NBD Capital unit and appointed Mohammed Wajid Kamran as general manager of the arm, according to an internal bank memo seen by Reuters.

Kamran was previously the bank's general manager of institutional and international banking and debt capital markets. It was unclear who would replace Kumar.

Emirates NBD, which is 55.64 percent owned by Investment Corporation of Dubai, is one of the major creditors to Dubai World, the state-linked conglomerate that completed a $25 billion restructuring in 2010.
