Six men in Britain aged 29 to 45 have been found guilty of multiple crimes involving a child sex ring that preyed on two schoolgirls for years.

Four other defendants were cleared Friday and the jury failed to reach a verdict on another man. The offenses took place between 2006 and 2012 in the small English city of Aylesbury, northwest of London.

The girls spent days giving evidence to the Old Bailey court. The charges included multiple rape of a child under 13, child prostitution and sedating a girl in order to have sexual activity. The guilty will be sentenced Sept. 7.

Britain has been plagued with several child sex abuse cases in recent years, including others like this that involve the grooming of young girls by older men.
