A Copenhagen court has convicted a 42-year-old woman of organising a brutal attack against her daughter’s ex-boyfriend after the daughter convinced her she had been raped.

On Wednesday, Copenhagen City Court sentenced the woman to 16 months in prison for the attack in April, when her daughter was 16.

After luring the former boyfriend into a trap, the two, together with the woman's younger brother, aged 24, and the boyfriend of one of the girl's friends, aged 18, forced him into a van and drove him to a wooded area in Gentofte.

There they carried out an hour-long ordeal that included putting a knife to his throat, stripping him naked, grabbing his testicles and forcing him to kiss his ex-girlfriend's shoes while they broke several of his fingers with a crowbar. At one point, the young man also had an electrical cord placed around his neck.

"You really messed up this time," one of the kidnappers told the victim before they put an object resembling a gun to his temple and counted down from three.

When they were finished him, the attackers returned the boy and his clothes to where they kidnapped him.

"They threw my clothes out of the car and yelled 'run!' Then the mother told me never to contact her daughter again and if I reported anything they would cut off my throat," the boy, who has asked to remain anonymous, told the tabloid Ekstra Bladet.

Brother expelled to Poland
The four attackers have been held in custody since April.

While the mother got the longest sentence, the daughter was sentenced to nine months in prison. The 18-year-old was sentenced to a year, and the 24-year-old got a year and three months and has been expelled to Poland.

The four offenders will also have to pay court costs and pay damages to the victim, who was able to show the court that he had 32 wounds on his body, 13 of which were to his face.
