The number of people seeking help to stop viewing images of child abuse has risen by 40% in the past year.
According to figures released by the Lucy Faithfull Foundation, a child protection charity which runs the Stop it Now! campaign, 36,443 UK people contacted Stop it Now! in 2017.
That,says the charity, represents a 40% increase on the 26,089 people who contacted Stop it Now! in the previous 12 month period.
A further 2,251 people called the anonymous Stop it Now! Helpline in the same period with concerns either about their own online behaviour, or that of a partner or family member.
Each country in the UK saw increases in the numbers of people contacting Stop it Now!: England saw a year on year increase of 41%; Wales saw an increase of 20%; Northern Ireland saw an increase of 40%; and there was an increase of 55% in Scotland.
The charity also said the sharp rise over the past year is partly explained by a campaign to tackle the viewing of child sex abuse images launched in October 2015.
