Actress Jamie Chung called in police officers to track down an obsessed fan who allegedly sent her threatening emails.

The Hangover Part II star received 100 messages, some of which contained death threats, from two separate email accounts within a week in August (15) and she called the cops, who launched an investigation to find the culprit.

The officers tracked both accounts to one address, and they obtained a search warrant for the house. They got in touch with the resident and ruled he lived too far away from Chung to be considered a real threat and the case was closed, according to TMZ.com.
