Democratic Party member, Howard Lam.

Democratic Party member, Howard Lam Tsz-kin, will serve his five months jail sentence after the High Court rejected his appeal today.

Lam was found guilty of a count of knowingly making to police officer a false report over claims he was kidnapped in August 2017 by the West Kowloon Magistrates' Courts and sentenced in March last year. But he was freed on bail pending appeal after sentencing.

At a high-profile press conference flanked by top Democratic party leaders in August 2017, Lam claimed that he was kidnapped from Mong Kok in broad daylight by a group of mandarin-speaking men.

He also claimed that they had stripped him half-naked and fired staples into his thighs before eventually dumping him on a beach in Sai Kung.
