Chicago girl apparently gang-raped on Facebook Live, police say

A 15-year-old Chicago girl appeared to be the victim of a horrifying gang rape -- by a group who streamed the attack on Facebook Live.

None of the roughly 40 people who watched the video called police about the attack, investigators said. Its the second time in months that Chicago police have investigated an apparent attack streamed live on Facebook.

Police finally learned of the attack after the girls mother approached Superintendent Eddie Johnson late Monday afternoon and showed him screenshots of the alleged assault, spokesman Anthony Guglielmi said. Johnson was leaving a news conference in the Lawndale neighborhood on the citys West Side.

€œHeres whats even more disturbing, more than the fact that they did this, there were so many people that saw it and didnt pick up the phone to dial 911,€� Johnson told WGN-TV. €œThats not right. Its just not right.€�

Johnson, who reportedly was €œvisibly upset€� after he watched the video, immediately ordered an investigation and the department asked Facebook to take the video down.

The girl was reported missing after she didnt return to her Lawndale home after going to the store on Sunday, the Chicago Tribune reported. Then, the girls uncle reportedly came across a Facebook Live video showing a group of boys assaulting the 15-year-old.

The girl was found Tuesday morning walking four blocks from her home. Police said she appeared to be in €œgood condition€� and was returned to her mother, the Tribune reported.

In January, four people were arrested after cellphone footage streamed live on Facebook showed them allegedly taunting and beating a mentally disabled man.

The suspects in that case -- Jordan Hill, 18, Tesfaye Cooper, 18, Brittany Covington, 18, and Tanishia Covington, 24 €“ were charged with hate crime and battery for allegedly torturing the white man for as long as 48 hours, while shouting racial and anti-Donald Trump slurs.
