London, Nov 21 Hollywood actress Jennifer Garner's alleged stalker is suffering from a mental disorder, says his aunt.

Steven Burky's aunt Maxine Burky revealed that the 36-year-old's obsession is the result of a psychological condition, but insists that he is not dangerous.

"He does have a mental disorder. He's supposed to be taking medication," the Daily Star quoted her as telling New York Daily News.

"It's been an infatuation for many years. He's not dangerous," she added.

Maxine also said that Burky's family sympathises with Garner.

"Something had to be done. I understand a stalker can ruin someone's life," she added. (ANI)
