- This is an event that we have been a little worried about it happening, I draw parallels to what happened in Trollhättan, says Anders Wiss, local police area manager in Varberg, who refers to the act at the school Kronan in Trollhättan 2015, which led to three people died and two were injured.

On Thursday, the police arrested a person, who is between 20-30 years old and previously convicted of arson.

According to the police, in addition to the fire in central Varberg, he had "arranged in his apartment for fire".

The perpetrator must have been wearing work clothes and a helmet with a visor and undressed garment after garment while leaving school.

On Thursday afternoon, the police updated the crime classification to attempted murder, attempted aggravated arson and arson.
