A prominent investment banker for JPMorgan Chase & Co. (JPM) jumped to his death from the roof of Chater House in downtown Hong Kong, the headquarters of JPMorgan’s Asian operations.

Witnesses told the South China Morning Post that said the banker, Li Junjie went to the roof of the 30-story Chater House in the city’s central business district and jumped.

The incident happened between 2 and 3 p.m. Tuesday in Hong Kong, or between midnight and 1 a.m. ET Tuesday.

Witnesses and emergency personnel saw the man leap to his death, the South China Morning Post reports.

Calls to JPMorgan’s North American headquarters were not returned.

Li’s death is the third unnatural or unusual death for a JPMorgan employee in three weeks, and the fifth odd death for a banker working in international finance in the past three weeks.

Former Federal Reserve economist Mike Dueker, 50, was found dead in an apparent suicide near Tacoma, Washington on Jan. 31. Dueker was chief economist at Russell Investments.

On Jan. 26, William Broeksmit, 58, a former senior manager for Deutsche Bank, was found hanging in his home, also an apparent suicide.

On Jan. 28, Gabriel Magee, 39, vice president at JPMorgan Chase’s London headquarters, apparently jumped to his death from a building in the Canary Wharf area.

Ryan Henry Crane, 37, executive director in JPMorgan’sglobal program trading, died Feb. 10. Details of the Stamford, Conn., native’s death have not been disclosed. He is survived by his wife, son and parents.

Crane’s death comes after a rash of suicides among three prominent bankers over the course of a week at the end of January and start of February, as well as the questionable suicide of a real estate finance executive said to have killed himself by shooting himself with a nail gun “seven or eight times.”
