Lindsay Lohan's monitoring bracelet goes off, but it's a malfunction

(CBS/AP) - Lindsay Lohan's court-ordered electronic monitoring bracelet went off on Monday, forcing probation officials to pay the actress a visit  at her Venice, Calif.,  home.

But when authorities arrived, Lohan, who is under house arrest, was found at her home watching TV and reading scripts, the Los Angeles Times reports.

The monitoring unit was replaced the day after the malfunction, Lohan's lawyer Shawn Holley said in a statement Thursday. 

Lohan was arrested twice for driving under the influence in 2007, and remains on probation for offenses. She is serving about 35 days of house arrest for violating her probation by taking a necklace from a Venice jewelry store without permission.
