The 29-year-old beauty shared a series of since-deleted tweets to her 900,000 followers on Twitter, in which she revealed that a gunman was hiding in her garden.
She is said to have written: “There is a gunman in my back yard. This is petrifying,” she wrote.
“Helicopters, police, dogs... And a crazy person.”
Ruby Rose went on to film the manhunt on her phone, sharing the footage police swarming over her backyard on Instagram.
In the video, she can be heard saying: "There's a policeman looking for a f***ing gunman, and there is a helicopter in my back yard."
About 20 minutes later, she revealed that the drama was finally over, and that a man had been apprehended by officers.
"Man arrested. Wow. Crazy. Annnd now I won't be watching horror films before bed anymore," she wrote.
Ruby, who has since deleted her video and posts, lives with fiancée Phoebe Dahl.
She recently enjoyed a huge surge in popularity after joining the cast of Netflix’s wildly popular prison drama Orange Is The New Black.
