A newspaper based in White Plains that drew nationwide anger after publishing the names and addresses of handgun permit holders last month is being guarded by armed security personnel at two of its offices, the publisher said Wednesday.

The increased security comes as the newspaper, The Journal News, has promised to forge ahead with plans to expand its interactive map of permit holders to include a third county in the suburbs of New York City, and local officials there have vowed to block the records’ release.

The armed guards — hired from local private security companies — have been stationed in The Journal News’s headquarters and in a satellite office in West Nyack, N.Y., since last week, said Janet Hasson, the president and publisher of The Journal News Media Group.

“The safety of my staff is my top priority,” Ms. Hasson said in a telephone interview.

The newspaper prompted a national discussion and a torrent of rage online after it published an interactive map of handgun permit holders in Westchester and Rockland Counties on its Web site last month. The Journal News had gathered the information from public records after the school shooting in nearby Newtown, Conn.
