EX-NTUC Income head Tan Kin Lian, the lightning rod for investors' complaints into possible mis-selling of Lehman-linked products, has appealed for help to track an alleged cyber-stalker.

Mr Tan, 60, said the stalker, who goes by the name of 'SiewKhim', has been sending him 'all kinds of insulting things... harassing me all the time' for a month now.

Initially, he said he blocked SiewKhim's comments as many were defamatory of him, as well as of other people and organisations.
