Two Swedish men who interrupted and detained convicted rapist Brock Turner have spoken out about what they saw the night he sexually assaulted an unconscious woman.
In a letter describing her response to her rape, Stanford rapist Brock Turner's victim thanked the two men who interrupted the assault and tackled her attacker.
Now those two men, Swedish PhD candidates Carl-Fredrik Arndt and Peter Jonsson, have spoken out about about the night they became heroes.
They told Swedish news outlet Expressen they had been riding their bikes to a party on the Stanford campus when they saw Turner, 20, behind the dumpster.
"We saw that she wasn't moving, but he was moving a lot," Mr Arndt told Expressen.
"We stopped and thought, 'that this seems very strange.'
"Peter asked him what he was doing, and I followed him. When he got up we saw that she was still not moving at all, so we asked something along the lines of: 'What the hell are you doing?'"
Turner then tried to run away but was Mr Jonsson tackled him and the pair managed to hold him until police arrived on the scene.
"I checked that the girl was alive, she wasn't moving at all, while Peter chased after him and managed to capture him maybe 30 metres from where we were," Mr Arndt said.
"We restrained him until the police got there."
The two men were witnesses at Turner's trial but have never met the woman they saved, but they described her letter as "very powerful."
"We haven't met her after the incident, but I saw her statement the other day and it was very powerful," Mr Arndt said.
"We're obviously very happy that we could help her."
There has been worldwide outcry after Turner was sentenced to just six months in jail for the assault, which left the woman with dirt and pine needles in her vagina.
There was also backlash against his father who wrote a letter about his son now no longer liked to eat, had never been violent and was suffering for "20 minutes of action".
But the victim has been widely praised for a letter in which she described her experience finding out what had happened to her and they way Turner's assault had affected her life.
SBS News has contacted Mr Arndt for comment and Mr Jonsson has said in a post on his Facebook page that he declined to comment.
Instead, he directed people to the victim's letter saying, "To me, it is unique in its form and comes as close as you can possibly get to putting words on an experience that words cannot describe.".
