Hilton Hotels Corporation today acknowledged receipt of a federal grand jury subpoena from the United States Attorney's Office for the Southern District of New York.

The jury is requesting documents relating to Hilton's employment of former employees of Starwood Hotels & Resorts Worldwide, Inc. and materials which Hilton returned to Starwood in February of 2009.

On April 16, Starwood filed a civil complaint alleging its former employees, Ross Klein and Amar Lalvani, and Hilton, unlawfully obtained and used Starwood information.

Hilton has placed Mr. Klein, Mr. Lalvani and their luxury and lifestyle team on paid administrative leave pending Hilton's review of the situation.

At this time, further development of the Denizen Hotels brand has been temporarily suspended.
