Nadja Benaissa sings with No Angels, Germany's most successful girl band
A singer from the German girl band No Angels has been charged with causing bodily harm for failing to inform sexual partners she was HIV positive.
Nadja Benaissa, 27, had sex with three people without telling them she was infected, prosecutors in Germany said.
One of them has since been confirmed as having contracted the virus, said the AFP news agency.
The singer was arrested in Frankfurt last year, shortly before she was due to perform a solo concert.
"She was well aware that any unprotected sexual contact can lead to the virus being passed on," prosecutors in the town of Darmstadt, near Frankfurt, said.
No Angels formed in 2000 on the international TV show Popstars, before recording a series of hits and emerging as Germany's most successful girl band.
They reformed in 2007 and competed in the 2008 Eurovision Song Contest, finishing 23rd.
