The man had previously been granted short furloughs from a psychiatric clinic in Sundsvall, but was recently granted leave lasting five hours.
The 43-year-old reportedly made contact with the girl’s mother via the internet and was able to get close to the little girl as a result, according to the Sundsvalls Tidning newspaper.
“It was due to our internal security procedures that this was discovered and we filed a complaint with the police. I take what happened very seriously,” said clinic head Erik Söderberg, who has launched an investigation into shortcomings in procedures related to the man’s care.
The man has been a patient at the clinic in Sundsvall for the last decade. On Wednesday, police took him in for questioning and then ordered him detained on suspicions of sexually molesting a minor and for serious child pornography crimes.
Police also found child pornography on a computer and mobile phone owned by the 43-year-old, who was housed in a wing of the clinic where computers and mobile phones are permitted.
