Lindsay Lohan sent to jail

A California judge sent troubled actress Lindsay Lohan to jail for 90 days yesterday for violating probation in a 2007 drug case by failing to attend alcohol education classes.

Lohan, 24, immediately burst into tears after the sentencing. She was not required to surrender immediately but will have to turn herself in on July 20. She will also be required to enter an in-patient rehabilitation programme after her release from jail.

The ruling came during a hearing set for the Mean Girls star after she missed a court date in May. She has been required to wear an ankle alcohol monitor since then.

Lohan was promoting a film project at the time at the Cannes Film Festival and claimed her passport was stolen.

Weeks later, the monitor issued an alert after Lohan attended the MTV Movie Awards and after-parties. Prosecutors called it an "alcohol-related" violation.

Prosecutors had hoped to introduce reports from the monitor to show the actress also had broken a court order against drinking imposed as part of her probation.

Superior Court judge Marsha Revel said during the hearing that the device showed Lohan's blood-alcohol content was 0.03.
