Lindsay Lohan is currently under investigation for grand theft. On Tuesday, police requested a search warrant for her home after suspecting a $2,500 piece of jewelry from a nearby store may be there. But before authorities acted on the warrant, an unidentified Lohan friend surrendered the jewelry to LAPD authorities. Lohan, who recently finished court-ordered rehab, is still under probation for a 2007 drunk driving case. She is scheduled to appear in court for a hearing on Feb. 25.
