Civil Aid Service officers stationed at the Lowu border yesterday found a mentally retarded teenage girl with a rucksack on her back wandering around the departure hall.
They questioned her but she was unable to tell them her name or where she came from.
The girl, aged 13 or 14, had no identification documents. She is of solid build and was wearing a yellow T-shirt, white shorts and red sandals when seen wandering at 2pm.
She was handed over to officers at a police post and taken to Northern District Hospital, where she was admitted for observation. No one had reported her missing by late last night.
The incident revived memories of the case of autistic teenager Yu Man-hon, 17, who has a mental age of two, who disappeared on the mainland on August 24, 2000, after he was wrongly sent across the border by immigration officials. He is still missing.
His mother, Yu Lai Wai-ling, spent many months on the mainland searching for her son and appealing to Guangdong's Public Security Bureau to help find him.
