Police are investigating "Mean Girls" star Lindsay Lohan in connection with the theft of a $2,500 necklace from a boutique, but the piece of jewelry has been returned, police said on Wednesday. The necklace was taken on January 22 from a boutique in the beachside Los Angeles neighborhood of Venice, police said. Surveillance video from the store shows Lohan wearing the necklace, according to media reports. Police began investigating the theft, and on Tuesday detectives obtained a search warrant for Lohan's Venice home, the Los Angeles Police Department said in a statement. But before detectives arrived to search Lohan's residence, the necklace was returned to a police station, officials said, adding that the investigation continues despite its recovery. An attorney for Lohan did not return calls for comment. Lohan recently completed a stay at the Betty Ford Center, in her fifth stint in rehab in three years, as a result of failing a drug test while on probation for a 2007 drunken driving and drug conviction. A December skirmish with a Betty Ford worker resulted in a police investigation, but prosecutors have not filed charges. The 24 year-old former child star from 1998 movie "The Parent Trap" has seen her career go off-track in recent years. She lost her starring role in an upcoming movie about 1970s porn star Linda Lovelace due to her personal problems. (Reporting by Alex Dobuzinskis: Editing by Bob Tourtellotte)
