One of the sex sadists snickered: "You have been raped."

As if it was nothing.

The shocking gang rape that was live-streamed on Facebook has triggered a crisis of conscience in Sweden.

The broadcast of three swarthy-looking men raping an unconscious young woman has forced the nation to question its liberal values.

The sickening rape aired Sunday morning and the question Swedes are asking is this: Why have the names and nationalities of the accused not been released?

One of the suspects is reportedly from Iran and has multiple criminal convictions, including assault, drug offences and theft.

Kurdish economist Tino Sanandaji slammed the government for sweeping immigrant crime under the rug, calling it an act of "ideological activism."

"There is no rational reason too good to refuse updating data on immigrant overrepresentation in crime," he said.

One person who say the livestream told the Aftonbladet newspaper that the men "pulled off her clothes and lay on top of her." One brandished a gun, pointing it at the camera and teasing viewers: "Come here then."

The snickering sickos then told the terrified woman to say she hadn't been attacked.

"He was very derisive and laughed throughout," another viewer told Swedish Television News.

An earlier victim of the trio relived her own 2015 ordeal.

"I had anxiety when I saw him," the 21-year-old told Swedish newspaper Expressen. "When I saw what was happening (in the video), I knew exactly how the girl felt."

Her ordeal was chillingly similar to the Sunday rape. Alone in an apartment with the men, they burst into the bathroom while she was taking a shower.

"I pushed him away several times and said no. I used all my strength to try to push him away, but in the end I gave up," she said.

"I had bruises and scratches all over my body, the throat and where he squeezed my breasts."

Her own complaint ended up in the trash bin after cops determined they could not say for certain if a crime had been committed.

Josefine Lundgren -- who viewed the attack -- was stunned more people didn't call cops.

"This is insane. It is only sick people who do such a thing. More people should care and act," she told Uppsala newspaper Niya Tidning. "What makes me most angry is that over 60 people sat and watched, but it was just me and one other who called the police.

"I hope these guys sit ashamed and realize what they have done."
