He is accused of sexually abusing a child in Pulheim, near Cologne, in December 2018. Police who searched his home in France seized large quantities of data and a large-caliber weapon, as well as a cannabis garden in the basement.
Prosecutors allege that the child was brought to him by the 27-year-old main suspect in the German case centered on the western city of Muenster, which emerged in June. There are now 22 suspects in the case.
The 27-year-old, who has two previous convictions for possessing child pornography, is accused of abusing his partner's 10-year-old son and offering him to other men.
