A 6-year-old boy's eyes were removed in Shanxi province, and local police have offered a reward of 100,000 yuan ($16,340) for information in the case.

The incident happened in Fenxi county on Saturday evening. Guo Bin, whose parents are farmers, was discovered missing at 6 pm, when he usually returns from playing outside to eat dinner.

Five hours later, a man who had returned from catching scorpions in the local mountains said he had seen what was possibly a boy twitching in the valley.
