Icahn says he will return his investors' money

The Boston Globe reports:

Carl Icahn, the billionaire investor, is returning all of the money that outside investors hold in his hedge funds.

In a letter to limited partners, Icahn said he did not want to be responsible to investors for "another possible market crisis," especially given the rapid increase in markets over the past two years. Icahn said he was also concerned about the economic outlook and political tensions in the Middle East.
