The Hong Kong government was last night trying to contact a resident stranded in Shenzhen with his baby son for eight months and who has resorted to begging. Cheung Kam-ming's mainland wife abandoned him and their newborn baby in January. Thieves then stole his identification documents and all his possessions. Mr Cheung, 45, has since been forced to beg on the streets. Last night, he said he hoped the Hong Kong government could help them. The administration tried to contact him yesterday after his story was reported by mainland media. The Hong Kong Federation of Trade Unions also sent two staff members to Shenzhen to help Mr Cheung. Chu Or, federation executive secretary, located Mr Cheung late last night and sent him to a hotel, promising to help him contact Hong Kong authorities today. Officers from the Immigration and Social Welfare departments have contacted Ms Chu. She said the departments would provide help after they verify the father's identity. Mr Cheung thanked the federation and the media for their help. 'I'm happy at last, my son can sleep under a roof for the first time in his life and we can at last take a proper shower,' he said. Mr Cheung, who lost his job as a deliveryman in Hong Kong three years ago, had slept under a footbridge in the Nanshan district of Shenzhen and ate leftovers from nearby restaurants. He could not return to Hong Kong because his son was born on the mainland and does not automatically enjoy right of abode. He fears he will be forced to part with the boy if he returns. Mr Cheung previously received welfare payments, but was disqualified by authorities because of his long absence from Hong Kong. 'I have been on the dole for two years and I feel too ashamed to ask the government for help again. I have a bad temper and don't have any friends or relatives to turn to,' he said. 'But no matter how bad a man I am, I hope I can be given one more chance. I want to bring my baby boy back and raise him in Hong Kong. The baby is innocent.' Mr Cheung hoped to raise enough money to pay the hospital where the boy was born so he can obtain a birth certificate, needed for a right of abode application. The Immigration Department said yesterday it had to verify Mr Cheung's claims before deciding how to help him and his son.
