Authorities are investigating the deaths of two Americans whose bodies were found at one of Hong Kong's most luxurious hotels, police and reports said Saturday.

Cleaning staff found the two men's bodies in a room at the Grand Hyatt hotel on Friday afternoon, a police spokeswoman said, speaking on condition of anonymity due to policy.

The cause of the deaths was not yet known and an autopsy was expected to be carried out later Saturday, the spokeswoman said. Police were not yet treating the deaths as suspicious, she said.

The spokeswoman confirmed both men were U.S. citizens, but said she did not know where they were from.

Dale Kreschler, press officer for the U.S. consulate in Hong Kong, said he could not release any details due to privacy concerns.

The five-star waterfront Grand Hyatt, where a standard harbor view room costs about $550 a night, is a favorite among Chinese and other state leaders when visiting the booming financial center of Hong Kong.

Grand Hyatt spokeswoman Karen Cheung said it was business as usual at the hotel. She said she could not reveal any information about the deaths because the investigation was still under way.
