Actress Sandra Oh has turned to the authorities for help after becoming a victim of identity theft.

The Grey's Anatomy star walked into a Los Angeles Police Department station on Friday to file a complaint after a hotel employee allegedly used Oh's social security number on tax documents.

Oh is said to have learned of the matter after Internal Revenue Service officials contacted her about unpaid taxes stemming from a hotel job in 2009.

Police have begun an investigation into the matter, according to TMZ.com.
