Carrie Lam appeals for Philippine president Duterte’s ‘personal attention’ in case of Hong Kong man serving 40-year jail sentence
Her letter calls on the president to push immigration authorities to find records believed to prove innocence of Tang Lung-wai

Tang Lung-wai, 47, has been languishing behind bars in the Philippines for 18 years. He entered the country as a tourist in June 2000 to meet a friend, but was arrested the next month for a drug offence.
It took 11 years for his case to make it through the legal system. He was convicted and sentenced but has maintained his innocence throughout.
Legislator Paul Tse Wai-chun, who is helping Tang and his family, said Hong Kong immigration records showed Tang was not in the Philippines when the offence he was convicted of took place.

Local police told the court they had been tailing Tang since early June 2000 in an anti-drug trafficking operation. But records suggested Tang only entered the country in mid-June that year.
