BELMONT, N.C. -- In September, a Belmont police officer saved a teenager's life after he tried jumping off a bridge onto Interstate 85.

"I wasn't going to let him die that day," said Cpl. Edward Mason, with the Belmont Police Department.

The amazing rescue was caught on his dash camera. For the first time since the incident, that local policeman spoke on camera.

"It got intense," said Mason. "He was straddling this legs over there. When he looked down I grabbed his arm and pulled him off."

In the dash cam video, you can hear the teen screaming. For Cpl. Mason, seconds seemed like minutes.

He distracted the boy with his cell phone then wrestled him to the ground. That's when muscle memory kicked in. The former marine was also at one point in his life a professional wrestler.

"It's all in the same movement," said Mason.

That movement saved a teenager's life. Cpl. Mason says the alternative was never an option.

"Traffic going into Charlotte was heavy and I thought this guy's not going to do this on my watch this day," said Mason.
