Dozens of protesters gathered in Hong Kong on Sunday to rally against a fellow activist's conviction for "assaulting a police officer" with her breast.

Ng Lai-ying was sentenced last week to three and a half months in prison for the incident, which took place during another protest this past March against mainland Chinese border traders. According to Ng, the officer had grabbed her breast during a scuffle, perhaps while trying to take hold of her bag. When she accused him of indecent assault, he turned the charge around on her.

"You used your female identity to trump up the allegation that the officer had molested you. This is a malicious act," deputy magistrate Chan Pik-kiu told Ng during her trial. 

The men and women who gathered outside the Wan Chai Police Headquarters on Sunday wore and waved bras as they challenged the absurdity of Ng's conviction, chanting "breasts are not weapons."

"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," Ng Cheuk Ling of the Hong Kong Women's Coalition on Equal Opportunities said during the protest. "Sexual harassment becomes a tactic for police suppression."
