WUHAN, Jan. 26 -- The former head of a securities firm in central China's Hubei Province fell to his death from an apartment building on Tuesday morning in what appears to be a suicide as he faced investigation for corruption.

Police in provincial capital Wuhan said they found a suicide note at the scene after Yang Zezhu, former chairman of Changjiang Securities, fell from an apartment on the 12th floor.

The Wuhan-based listed firm announced about three weeks ago that Yang was under investigation for "suspected violations of discipline."

Yang served as head of the provincial state-owned assets supervision and administration commission before taking up the post at Changjiang Securities in December 2013.
