A man was jailed for four years for setting fire to his neighbour's flat in Sham Shui Po last year. Choi Siu-chee, 61, previously pleaded guilty in the Court of First Instance to one count of arson. He was accused of starting a fire at the flat in Lai Kok Estate on August 26. The court heard the mentally ill Choi lived opposite the victim, 54. When the woman opened the door for her visiting daughter, a bottle containing an inflammable liquid was thrown into the flat, triggering a fire. The mother and daughter suffered slight injuries.
