The life of a three-year-old boy was saved at a swimming pool by a nine-year old after the younger boy was noticed to be drowning.

The whole incident which was captured on video showed the three-year-old boy as he struggled to stay afloat until he sank underwater while people around him played.

After nearly three minutes, nine-year-old Colby noticed the boy was still underwater and dived in to pull the boy out.

In an interview with ABC News he said, “I thought, wait a minute, he’s underwater, and I don’t even think he can swim.”

Colby’s mother who is a nurse, gave the three-year-old CPR to revive him.
