The sudden disappearance of a 33-year-old woman in London and the arrest of a senior police officer on suspicion of her murder has ignited a national conversation about harassment and the abuse of women in the U.K.

Sarah Everard, a 33-year-old marketing executive, had last been seen on the evening of March 3, as she was captured on doorbell video footage walking home from a friend’s house on a main road near Clapham, south London at around 9.30 p.m. Her family said that it was uncharacteristic of her to not be in contact with her friends, and alarms were raised over the last week over her disappearance.

On Tuesday, a serving officer in London’s Metropolitan Police (Met) was arrested at a house in Kent on suspicion of murder following Everard’s disappearance. The Met said that the officer is in his 40s and part of the Parliamentary and Diplomatic Protection Command. In a televised statement the following day, the head of the capital’s police force said that officers searching a woodland area near Ashford in Kent, the county bordering south of London, had found “what appears to be human remains” in the search for Everard. “Sarah’s disappearance in these awful and wicked circumstances is every family’s worst nightmare,” said Cressida Dick, Commissioner of the Metropolitan Police.
