Wall Street Journal Gets Powdery Letters

Police have evacuated the mailroom and another floor at the Dow Jones Inc. building in New York City after reports of envelopes that contained a white powder.

Police say at least four envelopes were opened and others were left unopened in the mailroom. The Wall Street Journal said it had received more than a dozen envelopes containing the substance.

The newspaper said on its Web site that the mail was addressed to several executives. The return address was Knoxville, Tenn.

It said at least 10 of the envelopes were being held in the mailroom of the Journal's Lower Manhattan headquarters. The evacuated floor is shared by newspaper executives and editorial page employees.

Field tests are being done on the substance. People who came into contact with the substance were isolated.

This incident follows a series of "white powder" mailings last fall which resulted in letters being sent to numerous media offices and financial centers. All of those envelopes tested negative for hazardous substances.

An internal Dow Jones email warns employees not to open any more mail, but stresses, "we don't think there is cause for alarm," reports CBS News.
