A boy aged just 5 is believed to have become the youngest person in Britain to be investigated by police for allegedly sexting.
The child and his parents were spoken to by officers after he took an intimate picture of himself and sent it to another child on an iPad, it has emerged.
The number of cases where children have taken explicit pictures of themselves and sent them to others has soared in the UK in the past two years, figures reveal.
But police and children's charities are concerned that the age of those being drawn into the practice is getting lower.
The 5-year-old in County Durham was spoken to by officers from Durham Constabulary last year, which is believed to have made him the youngest person to be investigated for taking and sending sexually explicit selfies.
