Protestors, including men, wore bras when they hit the streets last weekend in Hong Kong to protest the imprisonment of a woman who bumped her chest against a policeman's arm.

The protesters gathered outside Hong Kong's police headquarters to protest the conviction of Ng Lai-ying who was arrested after "assaulting" chief inspector Chan Ka-po with her breast during a rally March 1.

She was found guilty on Thursday and sentenced to three and a half months in prison, according to Al Jazeera.

Protesters chanted "breasts are not weapons" and said that the ruling aginst Ng was ludicrous.

"I believe we are all baffled as to how a breast attack works," said Ng Cheuk Ling, a 24-year-old activist with the Hong Kong Women's Coalition on Equal Opportunities, according to CNN.

"It's ridiculous and alarming that the judge didn't just convict the protester of assaulting police with her breast, but that her seeking help was also considered part of the assault," she told CNN. "Should we silence ourselves in the face of sexual violence? If this sets a precedent, the police will not only abuse their power but also strip women of their rights to take part in protests. Sexual harassment becomes a tactic for police suppression."

Lai-ying told the court that she yelled "indecent assault" out of fear immediately after Ka-po's hand landed on her left breast after failing to grab the strap of her bag, the South China Morning Post reported, according to AFP.

However, local magistrate Michael Chan Pik-kiu rejected the claim and accused her of lying.

"You used your female identity to trump up the allegation that the officer had molested you. This is a malicious act," said Pik-kiu, adding that Ng's accusation harmed the officer's reputation.

Pro-democracy legislator "Long Hair" Leung Kwok-hung said the sentence was an "insult to all the women on this earth."

"Breasts are the origins of human beings; no one can survive without the breasts of their mothers," he told CNN. "I think if anyone on this earth treats the breasts of women as a weapon, it's totally outrageous."

China might not be sure if breasts are weapons, but a British woman proved that if they're big enough, they can be used as airbags.
