Hotel heiress Paris Hilton was released from prison today for medical reasons after serving just over three days of a 23-day sentence.
Officials said she will be confined to her home for 40 days.
The Los Angeles County Sheriff's office said Hilton had been "reassigned" but declined to identify her medical condition for privacy reasons.
Hilton (26), a symbol of privilege and American celebrity culture, was serving a sentence for violating probation after being caught driving with a suspended licence. She will have to wear an electronic monitoring device on her ankle to ensure she does not go out for the next 40 days.
One reporter described Hilton's job as going to parties and events and asked if she would be allowed to leave her home for work, just as lifestyle media star Martha Stewart could during her five months under house arrest for insider trading.
"My understanding is that she's confined to her home with an ankle bracelet, she cannot leave that facility," said a police spokesman. "She will fulfill the remainder of her time confined to her home."
The Hilton Hotel heiress was originally sentenced to 45 days in prison. That was later reduced to 23 days under state sentencing guidelines.
