Christina Applegate`s fiance got death threats

Los Angeles: Actress Christina Applegate`s musician fiance Martyn LeNoble reportedly got death threats on Twitter.

LeNoble, 43, got threatening messages on Sep 20 and the sender looks like someone obsessed with Applegate, reports a website.

The couple has been engaged for the past two years and has a one-and-a-half-year-old daughter, Sadie Grace LeNoble.

The sender accused the musician of stealing the actress away and tweeted: "You stole (Christina) away from me. If not for you she would be mine... I will not accept this. I am going to kill you!"

The couple have filed a complaint with the Los Angeles Police Department (LAPD) and a search warrant has been issued.

The sender has also warned LeNoble not to take the issue lightly.

"I`m going to bust your head in for taking her away from me! Be afraid, be very afraid! You think this is a joke? I want to see how funny you think I am when I blow your f**king head off!" the sender wrote.

The big problem LAPD is facing is that Twitter is very anonymous. According to the search warrant, LeNoble could not recognise the Twitter profile of the sender. Now Police is trying to access Twitter`s records of the profile that have been deleted.
