Driver Confronted After Swerving Into Passing Motorcycle: 'I Don't Care'

Police in Atlantic City, New Jersey, have arrested a man who was seen in a Facebook video knocking a homeless woman unconscious at a local park. 

The Press of Atlantic City reports that cops were able to track down Iben Hunter, 25, Monday morning after the video was seen hundreds of thousands of times over the weekend. 

The video shows some sort of argument between Hunter and the woman before the brutal punch. 

A man behind the camera then laughed and yelled "It's over!"

Police say the 45-year-old victim suffered critical head injuries, but has since regained consciousness at a local hospital. 

Hunter, who has reportedly been arrested five previous times since age 18, was charged with aggravated assault and is being held on $100,000 bail.
