Meghan Markle’s estranged half-sister Samantha Markle has reportedly been placed on a police watch list.

According to Scotland Yard’s website, the Fixated Threat Assessment Centre helps “assess and manage the risks from lone individualswho harass, stalk or threaten public figures.”

“You can’t protect someone like the Duchess of Sussex without knowing the background of her family. But someone like Samantha presents a risk rather than a threat. She is not committing criminal offenses, but she is causing concerns for the royal family,” a Scotland Yard source reportedly told the outlet.

“Samantha could make a scene and create headlines with her actions — and let’s face it, she’s kind of already done that,” the insider added.

Although Scotland Yard has declined to comment on the report, Samantha has denied it, telling theSunday Times, “I would only say that is ludicrous. I’m not a reputational risk.”

Samantha — the daughter of Meghan’s father,Thomas Markle, from his first marriage — has been outspoken since Meghan first stepped onto the royal stage. Neither Samantha nor Thomas, 74,attended Meghan’s weddingin May.

In addition to telling the press that she was writing a memoir titled The Diary of Princess Pushy’s Sister, Samantha later took responsibility for arranging Thomas’staged paparazzi photosin the weeks leading up to the royal wedding — about which Thomasadmitted he lied to Harry.

Samantha went on to confess that she had been “cashing in” on Meghan’s fame.

“Let’s face it — we all have to survive. Money makes the world go round, so if you want to call that cashing in, that’s fine, but I think no one in media would refuse a paycheck for talking about the royal and, as a family, we’re not subject to royal protocol,” she toldGood Morning Britainin July.

Addressing Meghan and Samantha’s relationship, a source close to the formerSuitsstar previously told PEOPLE that “Meghan has no relationship with her half-siblings, nor has she ever had one.”

Since the wedding, Samantha has amped up her public criticism of Meghan, who is currentlyexpecting her first childwith Harry.

“How about you pay tribute to your own father?!” Samantha wrote on Twitter in July, according toPage Six. “Enough is enough. Act like a humanitarian, act like a woman. If our father dies, it’s on you Meg!”
