According to police, a 15-year-old girl was with a group of friends when she accidentally fell into the river. Another teen, a boy, jumped in to rescue her.
"She banged her head and got unconcious, so my boyfriend got into the cold water," said Carmen Garcia.
He managed to get the girl out, but soon the cold water started to sap his strength, and he needed to be rescued.
The rest of the group quickly grabbed some broken tree limbs and eventually pulled him to safety before rescue crews arrived.
"We tried to keep him as warm as possible," said Garcia. "I was really scared. I thought he was going to die."
The victims were rushed to Hahnemann University Hospital.
The Philadelphia School District tells Action News both teens should be fine. The girl involved in this incident goes to Edison High School.
It's unclear why the teens were along the river at that time.
