Around 300 protesters, mostly female, descended on the Mexican capital's prosecutor's office on Monday, BBC News reported.
Armed with pink glitter and spray paint, they advanced on the building, smashing its door and leaving a pig's head outside.
The protests were sparked by two recent rape cases.
The first involves a 17-year-old girl who said four policemen raped her in their patrol car in Azcapotzalco, in the capital's north, on August 3. The second concerns a 16-year-old girl who said a policeman raped her in a museum in the city center days later.
On Thursday, a police officer was arrested in connection with the second case. So far, no arrests have been made in relation to the first.
Outraged by the alleged misconduct by police, the protesters chanted "justice" and "they don't protect us, they rape us" at officers.
During the protests, Mexico's Security Minister Jesús Orta Martínez was covered in pink glitter when he attempted to assure the women both cases would be properly investigated.
Claudia Sheinbaum, Mexico City's first elected female mayor, described the protest as a "provocation."
"They wanted the government to respond with violence. But we're not going to do that," she told reporters.
Violence against women is prevalent in Mexico. United Nations figures show an estimated nine women are killed every day in the country.
