A New York City hotel chain auditor has been charged with stealing hundreds of guests' credit card information and selling it to a man accused of using it to buy $840,000 worth of airline tickets and other items.

Lukasz Kruk and Barry Herndon pleaded not guilty to grand larceny, identity theft and other charges Friday.

The Manhattan district attorney's office says 237 accounts were compromised over three years.

Prosecutors say Kruk was an auditor for the Amsterdam Hospitality Group and had access to guests' credit card data. They say Herndon bought tickets for himself and other people with information Kruk took.

Amsterdam Hospitality Group runs eight boutique hotels in New York City, Asbury Park, N.J., and Charlotte, N.C. Its representatives haven't responded to a request for comment.
