A judge doubled Lindsay Lohan's bail to $200,000 Thursday after she violated terms of her release, according to The Associated Press.

Judge orders Lindsay Lohan to wear alcohol monitoring bracelet

Judge Marsha Revel determined that the 23-year-old actress' bail should be raised after receiving results from the court-ordered alcohol monitoring bracelet. It is unclear what caused the bracelet to go off. A prosecutor and Lohan's lawyer told the AP earlier Tuesday they were awaiting information about that.

The bracelet is designed to test the skin for alcohol every half-hour by sampling a person's perspiration, and there are sensors that check for tampering.

Lohan appeared at MTV's Movie Awards Sunday, and the AP reported that she attended at least one of the after-parties.

Arrest warrant for Lindsay Lohan recalled

Upon her return from Cannes, Lohan appeared in court where Revel issued mandatory drug testing along with the bracelet, which Lohan must continue to wear until a July hearing.

Lohan has been on probation since August 2007 after pleading guilty to drug charges and no contest to three driving charges.
