US actress Lindsay Lohan has been taken into custody in Los Angeles to serve a jail sentence for probation violation.
The 24-year-old was handcuffed and sent to a women's prison south of the city after appearing before a court.
She is expected to serve less than the 90-day sentence imposed earlier this month because of jail overcrowding, and is likely to spend it in isolation.
Lohan, who was jailed after failing to attend alcohol education classes, will enter rehabilitation after her release.
