The comedian has told of how her partner wrangled with an intruder who tried to steal her laptop, which contained scripts for her upcoming show.
She posted a clip on her Instagram Story showing police at her London home, with the caption: “Cool to be robbed tonight by a masked man in our home.”
In another clip, Katherine could be seen holding her laptop, telling fans: “This is why I love Bobby K (Kootstra), he got in a fight and wrestled back my Netflix series, all my scripts.”
She pointed out there were now spots of blood on the computer.
Suggesting she had been shaken up by the incident, she joked: “That’s fine I never liked sleeping anyway,” she joked.
The star later revealed that a ring had been stolen.
Sharing an image of the item on Twitter, she asked her followers: “Is there a way to circulate this foreshadowing ring around pawn shops that the masked man stole before he was tackled into the street?”
Katherine has previously made two stand-up specials for streaming service Netflix.
The first, in 2017, was titled Katherine Ryan: In Trouble, which she followed up earlier this year with Glitter Room.
Katherine has been dating her former childhood sweetheart Bobby for around nine months.
The pair reunited nearly two decades on from their first relationship after a chance meeting while she was filming the BBC’s Who Do You Think You Are? in her hometown of Sarnia, west of Toronto.
Katherine has been living in London for more than a decade with her young daughter, Violet.
