New York City police say the underage daughter of Demi Moore and Bruce Willis was caught drinking in public and carrying fake identification.
The New York Police Department said on Tuesday that officers found 20-year-old Scout Willis sipping a beer on Monday evening in Union Square in violation of an open-container law.
Police say she also showed them a fake ID - a misdemeanour.
Willis was arrested and taken to a local police station and released with a ticket ordering her to appear in court on July 21.
Bruce Willis's representative declined to comment on the arrest.
Scout is the second of Moore and Willis' three daughters together. The couple divorced in 2000.
