Pic posting and swapping of children has taken place on the social media outlet
An under cover investigation carried out by the BBC has found secret groups of paedophiles actively posting and swapping pictures of children online.
Images on the 'closed' Facebook groups appeared to have be taken from newspapers, blogs and even clothing catalogues.
According to the BBC, there are also photographs of children and a video of a children's dance show.
Of the twenty images reported to Facebook, four were taken down, the others remained up.
It told the BBC that the pictures of the children, some of them sexually explicit ones, did not breach "community standards" .
