A man has been arrested, suspected of having forced a high school student in Västerås to send intimate pictures of himself, the police write on their website.
The man worked at the school that the student attended and is suspected of having committed the crimes from mid-December last year until he was arrested last week.
He is now suspected of gross exploitation of children for sexual posing and child pornography offenses.
No other student at the school is believed to have been affected.
