CCTV footage captured a delivery worker in Inner Mongolia, China, accidentally striking a colleague while unloading packages from a truck.

The video, recorded on October 15, shows two workers stacking boxes on a flatbed lorry when one of them throws a white cylindrical package toward the ground. As a nearby worker steps out of a forklift to collect the item, it hits him on the head, causing him to stumble forward from the impact.

The two workers on the truck appear momentarily stunned before checking on their colleague and continuing their duties. Fortunately, the injured worker did not suffer any serious injuries.
