BERLIN (AP) — A 33-year-old Spanish man has been found guilty of repeatedly raping a young German boy whose mother offered him for sale to pedophiles on the internet.

The dpa news agency reported Monday the man, whose name wasn't released for privacy reasons, was sentenced by Freiburg state court to ten years in prison and fined 18,000 euros ($20,800). He admitted paying the woman and her boyfriend 10,000 euros ($11,560) to rape the boy multiple times in the town of Staufen.

A verdict against the 48-year-old woman and her 39-year-old partner is due Tuesday.

The boy, now 10, was offered in the "darknet" online for some two years starting in 2016. Police learned of the case through an anonymous tip in 2017.

Three German men and one Swiss citizen have already been convicted.
