Arrested after Facebook flagged a private image to his wife?

A user claims UK police arrested a man after Facebook reported a private image he had sent to his wife. The claim is unverified, and the material gives no details on the image, the charge or the platform's role. If accurate, it shows how automated scanning of private messages can turn an exchange between spouses into a police matter. It also shows how online-safety rules reach into places most people regard as entirely personal.
