Activists participating in a Sunday kiss-in against homophobia in Peru claim police assaulted demonstrators, Peru.com reported.

According to the gay rights group behind Sunday's Besos Contra La Homofobia (Kisses Against Homophobia), Movimento Homosexual de Lima (MHOL), about thirty police officers rushed in to disperse about a dozen gay and lesbian couples staging their demonstration in Lima's Plaza de Armas.

One woman, Alicia Parra, 33, who refused to leave the plaza was reportedly struck by an officer in the back of her skull. She received 10 stitches to repair her injury.

“We, lesbian, gay and bisexual couples, were walking by the Plaza de Armas and we kissed, and then the police arrived and they began to beat us and they used pepper spray; never did they warn us, or give us a reason,” Veronica Ferrari of MHOL said.

Members of the group on Monday said they would bring charges against the Peruvian national police force (PNP).

In a four-minute-fifty-five-second video posted on YouTube, demonstrators are seen chanting “No to homophobia” as officers push around a young gay male couple in an embrace. In another shot, police are seen chasing after a female as she takes cover in a coffee shop. (The video is embedded in the right panel of this page.)

The group said previous demonstrations had ended peacefully.

Comments in support of recognizing gay unions by the nation's leading presidential candidate, Alejandro Toledo, have reignited a debate over gay rights in Peru.
