The practice of female genital mutilation (FGM) is mostly thought to be limited in countries like Africa, but a recent investigation by The Sunday Times found that as many as 100,000 women in Britain have undergone the debilitating procedure.

And the worse part is that these medical practitioners in the U.K. are performing the extremely illegal procedure (where the crime carries up to a 14-year prison sentence) on girls as young as 10. Guardian reports:
Investigators from the Sunday Times said they had secretly filmed a doctor, dentist and alternative medicine practitioner who were allegedly willing to perform FGM or arrange for the operation to be carried out. The doctor and dentist deny any wrongdoing.

The practice, which involves the surgical removal of external genitalia and in some cases the stitching of the vaginal opening, is illegal in Britain and carries up to a 14-year prison sentence. It is also against the law to arrange FGM.

The procedure is widespread across parts of Africa. Victims are rarely given anaesthetic and frequently suffer long-term damage and pain.

Research suggests that every year more than 22,000 girls in the UK and up to 6,000 in London are at risk of the potentially fatal procedure.
