A heroic security guard ran to stop a speeding three-wheeler with a two-year-old boy inside from hitting a shop's glass door after he accidentally started it in central China.

The CCTV video, shot in the city of Shangqiu on September 19, shows the man named Zhu Naizhong suddenly running towards an electric three-wheeler which is speeding down a road and grabbing the vehicle right before it crashes into a shop's glass door.

The two-year-old boy sitting inside the three-wheeler can be seen holding the handle and landing onto the ground safely.

According to reports, the boy's mum left the boy alone on the three-wheeler to do some shopping, but she forgot to take the key out. The boy then touched the switch and started the vehicle accidentally.
