A heroic woman grabbed a man's arm tightly to save him from jumping off a bridge in central China.

The CCTV video, filmed in Zhengzhou City in Henan Province on March 23, shows a man squatting on the side of a bridge while a female member of staff from the bridge management authority is standing beside him to try to comfort him.

However, the man suddenly stands up and climbs over the guardrails when the woman was calling for help on the phone.

The woman then immediately grabs the man's arm before he can jump off, and two men in a passing vehicle come out to help her pull the man up together.
