A Chicago teen pulled his older sister from a white van during an attempted abduction, police say.

Diavonnie Ingram, 15, and her 13-year-old brother Devonte were walking through an alley when a man in a white van grabbed Diavonnie and pulled her into the vehicle.

That’s when Devonte sprang into action, grabbing his sister by the ankles and pulling her from the van.

"My son to me is my hero, as well as hers," their mother Felicia Wings said. "And he's always going to be our hero because he saved her life."

The suspect is still at large. Authorities described him as a clean-shaven Hispanic man with dark, curly hair who is between 20 and 30 years old. Police say he’s between 5-foot-9 and 6-foot-2 and likely weighs about 190-200 pounds. He was wearing a black and white Adidas jacket and black construction boots at the time of the attempted kidnapping.

The white van’s license plate was covered, but authorities say the vehicle is dented.
