Watch | 4-year-old wanders on highway

Footage has emerged from China of a four-year-old boy wandering onto a motorway by mistake while looking for his parents. The video, filmed in Xiangxi Tujia and Miao Autonomous Prefecture, Hunan Province on, shows a police officer and a local villager carrying the boy away from the road, before helping him to find his mum and dad. It took them an hour, but they did eventually reunite the boy with his parents.
