Four men are in custody in the Netherlands, suspected of deliberately injecting homosexual men with HIV-infected blood.

The attacks occurred in the town of Groningen, Expatica News and ANP said Wednesday.

Police say the men met their victims in Internet chatrooms and lured them to sex parties. The victims allegedly were drugged with GHB and then injected with the HIV-infected blood.

Five victims between the ages of 25 and 50 have reported to the police so far. Officials say they believe there are more victims out there.

The suspects, three of whom are homosexual, are charged with premeditated grievous bodily harm and face up to 16 years in prison.
