"Keeping Up with the Kardashians" star Kris Jenner has been receiving death threats from a woman identified as Christina Brankston.

The Kardashian-Jenner matriarch is currently at the center of a huge FBI investigation after officers allegedly raided a Four Season Beverly Hills hotel room on Friday and seized the woman's electronic devices, according to Mirror UK.

Jenner has been receiving death threats and countless phone calls that have been harassing her nonstop and now, authorities have confirmed that the woman has been served a warrant. However, they did not provide details following the investigation and confirmed that she was not arrested, E! News reported.

TMZ was first to report that Kris received at least 300 calls from Brankston using one single number, within one day and made various threats.

The same publication confirmed that the woman's cell phone, laptop, iPad and iPod Touch have all been seized by the FBI.

Meanwhile, Brankston opened up to Radar Online and said that she was not responsible for the threats. Rather, it was her friend who has been using her devices and making the calls for the past eight months.

"On Friday morning I was asleep in my hotel room when I heard a knock on the door. I asked who it was and they said FBI. I opened the door and I was told to turn around, and I was handcuffed, facing 12 agents with guns pointed at me," she said.

However, her family and friends confirmed that she has been obsessed with Jenner and added that the obsession has been ongoing for months now, Aceshowbiz noted.

At one point, Brankston even went to Los Angeles to try and meet up with Jenner. Additionally, in a video obtained by the TMZ, Brankston was featured saying "I love you, Kris" repeatedly while on board a roller coaster in Disneyland.

As of late, Jenner has not yet released an official statement following the incident.
