French authorities have arrested a man over threats to to kill actress Jodie Comer.

The Killing Eve star alerted authorities after receiving a series of threats online. According to the Daily Mail, an individual began harassing Comer on social media before also harassing her immediate family online.

The actress reportedly received an array of threatening messages from the suspected stalker, including one which said: "I am coming to England to create carnage."

A 44 year old man was arrested last month in the city of Roubaix, in the north of France. It’s believed that the man’s location was tracked by technology experts, before armed officers stormed his home during a dawn raid and seized a selection of computer files and technical equipment.

Confirming the threats, prosecutors in Lille said they were of "great concern."

A spokesman for the prosecutors said: "Following an official approach by the British authorities, a man was taken into custody for acts of harassment against an English actress."

Comer and her family first contacted police in the UK about the threats, which were sent via email and social media, on June 30th.

The actress, who most recently starred alongside Ryan Reynolds in Free Guy, has kept a low profile on her social media accounts since an investigation into the threats began. She has resumed posting in recent days while limiting those who can respond to her posts online.
