Authorities say a brutal “knock out game” perpetrated by roaming gangs of youths is responsible for 6 deaths across the country.

In one notorious incident in 2012, a 15-year-old boy was arrested for sucker punching a well-liked teacher in Philadelphia. Since that incident there have been other cases of similar violence against men and women in New York and New Jersey.

In the latest incident in Midwood, a woman was attacked in broad daylight by a young man who walked up behind her, balled up his fist and hit her with all his might on the top of her head then ran off.

The woman, who was loaded down with shopping bags, was not robbed by her assailant.

“She had her purse, she had bags from department stores. There was not even an attempt to take anything from her. It was just a wanton act to hurt another human being,” the victim’s daughter told CBS 2’s Dave Carlin.

“How would you feel if this was happening to you or a member of your family?” she said, “If you don’t like it to happen to you or a member of your family, don’t do it to someone else.”

Psychologists say teens and young men who sucker punch their victims with enough force to knock them out are emotionally troubled people who were probably bullied in school or beaten by their parents as children.
