The police unit that protects children while they are on the internet says there has been a large increase in the number of reports it has received. The Child Exploitation and Online Protection Centre - known as CEOP - believes the rise is due to greater awareness of the problem. There were 6,291 reports last year - an increase of 880 on the previous year. More than 1,500 were related to the online grooming of children. Zoe Hilton, the head of safeguarding and child protection at CEOP, said the rise was down to the fact that more sites now worked with them and the introduction of a panic button meant it was easier to report incidents of concern.
