Scottish police said on Sunday they are investigating a report of an “online threat” made to writer JK Rowling after she tweeted her conviction for the stabbing of Salman Rushdie.

The Harry Potter creator said she felt “very bad” after hearing the news and hoped the novelist “was okay.”

In response, one user told her “don’t worry, you’re next.”

After sharing screenshots of the threatening tweet, Rowling said: “To everyone who is sending messages of support: thank you, the police are involved (they were already involved in other threats).”

A Scottish police spokeswoman said: “We have received a report of an online threat and officers are carrying out investigations.”

Rushdie, 75, was preparing to deliver a lecture on artistic freedom Friday in western New York when a man stabbed the Indian-born writer, who has lived with a bounty for his head since his 1988 novel “The Satanic Verses” prompted Iran to urge Muslims to kill him.

The alleged attacker, Hadi Matar, 24, pleaded not guilty to charges of attempted murder and assault in a court appearance on Saturday.

Rowling has been criticized in the past by trans activists who have accused her of transphobia.
