Six police officers have been jailed for 25 to 41 months each for perverting the course of justice relating to an operation involving homeless people in 2020.

The officers – Leung Fei-pang, Pong Chun-sze, Lam Wah-ka, Mok Chi-shing, Wan Pak-sze and Chan Sau-yip – were convicted last month of falsely accusing a man of possessing drugs, and blocking CCTV cameras during the operation in Sham Shui Po.

At Thursday's sentencing, District Court judge Kathie Cheung said perverting the course of justice is a serious offence, and the officers had abused their powers and undermined public confidence in the force.

Lam, a sergeant and the most senior officer at the scene, was imprisoned for 41 months; Mok, Wan and Chan each received 37-month sentences; and Leung and Pong were each given 25-month jail terms.
