An overzealous Jennifer Lawrence fan has been jailed after showing up outside the actress' home in Kentucky and sending her brother a threatening message.

Han Cong Zhao is being held at the Jefferson County Jail after turning up at The Hunger Games star's family home in Louisville on 18 April (13).

He is also accused of attempting to contact the actress' brother Blaine more than 200 times and leaving him a voicemail message stating, "I find you or you come to me. You got me really upset. When I am upset, wait and see what happens."

The 23-year-old former university student from Canada was charged with stalking Lawrence's relatives, and has been ordered to have no contact with the family.

According to USA Today, he has pleaded not guilty, pending a trial set for 23 July (13).

In a statement, the Oscar winner's lawyer Brad Hume said the Lawrence family appreciates the "responsiveness and professionalism" of the local police.

Hume adds, "Beyond that the Lawrences asked that their privacy be respected. This is not something they invited."
