AN actor found in possession of a stun gun was yesterday sentenced to two months' jail. Kong Kwok-wai, 30, pleaded guilty to possessing a dangerous weapon and a cartridge case. Police found the items in his flat in December 1993. The District Court heard there was no evidence to indicate the stun gun had been used for unlawful purposes, but Deputy Judge Candy said it was difficult to imagine what legitimate purposes such a dangerous weapon could be used for. Kong told police he was simply looking after the gun for a friend. Judge Candy said police evidence suggested Kong had not attempted to hide the weapon, but a suspended sentence for such a serious offence would be inappropriate.
