This Morning viewers were left feeling concerned for one guest as they tuned into the ITV show on Monday morning.
Laura Bates appeared on the show to talk to hosts Eamonn Holmes and Ruth Langsford about the tragic Plymouth shooting which occurred last week.
Jake Davison gunned down five victims, including his mum and a three-year-old girl in a 12-minute massacre, before turning the gun on himself.
It's since been reported that the 22-year-old identified with a cult of twisted and miserable women-hating extremists linked to a series of terror attacks around the world.
Davison, 22, repeatedly cited incels, “involuntary celibates”, in his ramblings on YouTube and Reddit, and complained about being a "f***ing fat" and "ugly" virgin and loner who never kissed a girl and couldn't get matches on Tinder.
Members of the incel movement - young men who hate women because they feel they are being oppressed by women due to a perceived lack of sexual interest - celebrated last Thursday's gun attack.
British security sources have said incels posed a growing threat in Britain, with the movement associated with at least six mass shootings and the murders of 46 people in the US.
Laura is the author of Men Who Hate Women: From Incels to Pickup Artists, the Truth about Extreme Misogyny and how it Affects Us All, and spoke about the worrying incels during her appearance on This Morning.
Eamonn said to her: "You infiltrating their ranks, then they found out that you are a woman pretending to be one of them. That must invoke fury from them?"
"Yeah so they've been looking for me since. There are men in these groups now posting pictures of themselves with weapons saying, 'which one of you is Laura Bates? I'm coming to get you, I'm coming to find you," Laura replied.
"They've been trying to hack mu email accounts, sending rape and death threats, threatening my family..." she continued, as Eamonn and Ruth looked on shocked.
"I think the i’d be more frightened if I was in the US," she added. "But I think there is danger and we have to take this seriously."
Viewers tuning in at home were left feeling worried for Laura and took to Twitter to comment.
"Pretty concerned for Laura's safety now she's on national TV talking about this. #ThisMorning," one person posted.
Another person wrote: "Laura please do stay safe. Not sure #thismorning should have allowed you to come on undisguised."
And a third added: "Wow Laura! Keep safe please #thismorning," while a fourth said: "We all should stand with Laura #thismorning."
This Morning airs weekdays at 10am on ITV.
