Chicago – Chicago authorities on Saturday said they had arrested a 14-year-old boy in connection with the sexual assault of a teenage girl by multiple young men that was seen on Facebook Live in March.

"Tonight, CPD (Chicago Police Department) arrested the first of several juvenile offenders in the Facebook sexual assault incident," the department's chief spokesman Anthony Guglielmi said on Twitter, adding that a news conference would provide further details on Sunday.

The mother of the victim of the March assault had approached police after an unrelated news conference and shown them images of her daughter being assaulted by five or six young men.

The mother said the girl's uncle had told her about a video on Facebook Live that showed the assault. The high school freshman had gone to the store and her mother became concerned when she did not return.

The March incident was among several in recent months in Chicago in which the social media site has played a role in broadcasting apparent crimes.
