A schoolgirl's obsession for a young man drove him to kill her, a court heard yesterday.
Fong Kin, 19, suffocated and throttled 17-year-old Hung Fong-ling after she turned vicious and threatened to have his younger sister raped, defence barrister John Haynes claimed.
Mr Justice Mohammed Saied jailed Fong for four years after he pleaded guilty to manslaughter on the grounds of diminished responsibility.
Mr Haynes described Fong-ling as 'an extrovert and perverse person unable to admit her faults'.
After Fong moved out of his family home and rented a flat in Yuen Long last April, she asked to move in with him on May 11.
'This headstrong young girl came to his flat almost as soon as she heard he had his own place,' Mr Haynes told the Court of First Instance.
