Sexting is the sending or receiving of sexually explicit messages, photos, or videos, usually by phone, which becomes a serious legal matter when it involves anyone under 18 because such an image is a criminal indecent image of a child.

In plain English

The sending or receiving of sexually explicit messages, photos, or videos, typically via a smartphone. When involving under-18s, sexting can have serious legal consequences.

Why it matters

Any sexual image of a person under 18 is a criminal indecent image, even if the young people are in a relationship. Police use Outcome 21 to record incidents without criminalising children where it is not in the public interest. UKCIS guidance helps schools respond proportionately.
