An envelope containing powder was opened by a Journal News employee Wednesday. "Emergency officials secured the room and the envelope, and the employee underwent decontamination procedures," John W. Barry reports.

Police determined the powder was nontoxic in preliminary tests. The building's landlord says the paper's mail will now be screened.

The incident may be related to Westchester County, N.Y., paper's decision to publish the names and addresses of local gun owners. Officials in Putnam County, N.Y., have said they will not fulfill the paper's Freedom of Information Act requests for the public records there. They plan to elaborate at a press conference today.

White Plains Public Safety Commissioner David Chong told Barry any connection between the powder and the gun map "would only be conjecture on my part right now." Since the map was published, the paper has hired armed security guards, and outraged readers have published addresses and personal information about Journal News and Gannett staffers.
