SAO PAULO — Brazilian police say a 12-year-old girl was gang raped at a party in Rio de Janeiro and her attackers posted images of the crime on social media.

Police Officer Juliana Emerique de Amorim told the G1 news portal Friday that they are looking for four young men in the attack earlier in the week in Rio's Baixada Fluminense district. She said the girl's aunt alerted authorities after she saw the images on Facebook.

Repeated calls seeking additional information from the police department rang unanswered Saturday.

A 16-year-old girl was raped in Rio's Morro do Barao slum by three men in a similar incident a year ago. Videos of that gang rape were also shared on social media.

Police found and arrested the three men earlier this year.
