CHICAGO - Chicago police are investigating an attack on a teenage girl after cellphone video shared online showed her being repeatedly struck by a group of people as onlookers laugh.
Police spokesman Anthony Guglielmi posted on Twitter on Tuesday that the video ``is beyond disturbing to watch and this young girl deserves far better.'' Guglielmi says the video has been forwarded to the department's Special Victims Unit and a criminal investigation is taking place.
The video was shared online by a person who wrote that she was a friend of the girl who was attacked. The post said the girl has a ``mental disability.''
The video shows several girls or young women beating the girl as she screams. WLS-TV reports the girl was treated and released at a hospital afterward.
