A district councillor familiar with disgraced public-housing tenant Yuen Kin-man has attributed his littering, which cost him his home, to an unhappy family life. Tuen Mun district councillor Chan Wan-sang's comment came after the Housing Department yesterday confirmed that Mr Yuen, the first public-housing tenant to be evicted for littering, had applied for interim housing. The Housing Authority issued an eviction notice on Mr Yuen last month after he amassed 17 demerit points under a marking scheme. He must leave his Yau Oi estate flat by October 20. Mr Chan met Mr Yuen more than a decade ago, around the time his wife left him. His two children - a son in his 20s and an 18-year-old daughter who lives with him - rarely stayed at the flat. 'He is alone most of the time,' said Mr Chan. Mr Yuen would become emotionally unstable when families living around him were enjoying happy moments, especially during festival times, he said. Mr Yuen, 47, who has spent four months in jail for throwing bottles from his 25th-floor flat, had accepted the councillor's suggestion that he make a public apology on the day he moves out, Mr Chan said. A Social Welfare Department spokeswoman said it had assigned a social worker to follow Mr Yuen's case. The department also recommended Mr Yuen apply for interim public housing - instead of living in a transit centre with a number of beds for residents - because he lives with his daughter. There was no limit on how long a tenant could live in an interim flat, the spokeswoman said. A Housing Department spokeswoman said the demerit points system still applied in interim housing, and approval for public housing would depend on a tenant's behaviour while in interim housing. Mr Yuen had not yet applied for public housing, the spokeswoman added. Mr Yuen could not be reached for comment yesterday.
