Hong Kong police will seek help from their mainland counterparts to find the parents of a mentally disabled boy dumped in a Lau Fau Shan street on Wednesday.
Crime squad officers suspect the boy - thought to be aged between five and seven - was smuggled into the city from Shenzhen by boat and then abandoned.
The boy probably has polio because he has problems walking, police say. 'He [also] fails to communicate when our officers speak to him and is thought to be mentally retarded,' a police officer said.
'He is unable to tell us his name or where he came from.'
The officer said the boy did not appear to have any injuries but medical tests would be conducted to determine the state of his physical and mental health.
The force's child psychologist would also try to talk to the boy to find out more information, the officer said.
The boy is being cared for at Tuen Mun Hospital.
He was found sitting alone outside a vacated hut near the waterfront in Fui Yip Street, Lau Fau Shan, at about 5.30am on Wednesday. A villager who called police told officers the child had been there since 4am.
Police said he had no identity documents. He is about one metre tall, weighs 16 kilograms and has short, black hair. He was found wearing a blue jacket, light brown shirt and blue trousers.
His description does not match any reports of children missing in Hong Kong so police will seek help through the force's liaison bureau to see whether mainland police have information about the child and whether he has been reported missing there.
Police said yesterday his parents had not been located and anyone with information should contact them on 3661 4641 or 3661 4810.
Another officer said it could have taken less than half an hour to smuggle the boy to Hong Kong from Shenzhen by boat.
