A Chicago teen was on life support after being hit in the head with a baseball bat in the Back of the Yards neighborhood on the city's South side.
The 17-year-old boy was followed by a red SUV while walking home, according to Police News Affairs office.
A male passenger then got out with a baseball bat and chased the teen until he caught up and hit him with the bat. Afterward, the suspect then got back into the vehicle and drove away.
The attack took place two blocks away from his school, Richards Career Academy and an investigating has been launched to see if it is school related but nothing has been ruled out.
The boy's mother told the Chicago Tribune that her son had been bullied by a classmate, but didn't know if there was any connection between that and the beating.
"He never told me he had problems," said Maria Rangel. "He didn't want me to worry."
The teen is listed in critical condition at Advocate Christ Medical Center in Oak Lawn with a brain injury.
