On Wednesday, Swedish Radio News revealed that the prosecutor had handled sensitive investigations involving children and youth.
"We've failed. It's a failure that this wasn't done earlier," director of public prosecution Marianne Ny tells Swedish Radio News.
Ny thinks that this revelation could harm the prosecutor's office reputation.
"We will control his work very carefully this time," deputy chief prosecutor Bengt Åsbäck says.
One of the cases that the prosecutor investigated concerned the so-called Hudikmappen, or the Hudik folder, a collection of digital photographs of nearly 30 teenage girls in Hudiksvall, a town in central Sweden.
The folder wound up online in 2012, against the girls' will, and were widely shared online.
