U.S. investigators probing a troubled Malaysian state investment fund have subpoenaed Goldman Sachs' former chairman for Southeast Asia, the Wall Street Journal reported, citing a person familiar with the matter.

The banker, Tim Leissner, who resigned from Goldman last month after the bank placed him on leave, worked on several large bond deals for deeply indebted 1MDB, or 1Malaysia Development Berhad, netting hundreds of millions in fees for the bank, the WSJ said.
