A 35-year-old HIV-positive man who might have consciously passed on the deadly virus to more than 200 sexual partners, has been arrested in Ancona, Italy.
Claudio Pinti, despite having been diagnosed for at least 11 years, did not take precautions nor warn his partners about his condition.
In a press conference on Wednesday, police said Pinti was a regular user of dating websites and might have infected more than 200 people.
He was caught after one of his most recent partners checked herself into hospital after feeling ill and discovered she had contracted the virus.
Authorities urged potential victims to contact police, and in a breach of usual practice, released a picture of the suspect so people could recognise him.
