Seven members of a Protestant sect in Bolivia have been sentenced to 25 years each in prison for raping some 100 women in an agrarian commune, the judge and prosecutors told the press.

An eighth man was sentenced to 12.5 years in prison for providing a narcotic that the men sprayed to render the women unconscious before raping them in their dormitories, said Judge Luis Enrique Perez.

“The victims were raped in a repeated manner. Among them, there were adults, children and elderly women,” prosecutor Freddy Perez was quoted as saying by El Dia newspaper. Records indicate that the men sprayed a substance derived from the belladonna plant normally used to anaesthetize cows through bedroom windows at night, sedating entire families.

They then raped the women and girls. The youngest victim was nine years old.
