Married man, 42, claims his Web message was just a joke, court told An online invitation to organise a 'flash mob' to gang-rape women has landed a married man in court. In the first prosecution of its kind, Johnny Chan Sek-ming, 42, pleaded not guilty yesterday to two counts of committing an act outraging public decency, and two alternative charges of using a computer with intent to commit an offence. Claiming it was 'merely a joke', Chan admitted he had posted two messages on the message board GOSSIP of the She.com site on August 13 and 15, inviting people to team up for a 'Flash Mob Rape', which he also referred to as 'Jack-Rolling', to gang rape women. His messages allegedly detailed the following: 'Flash mob rape is formed by 5-6 boys, specifically intercepting single females. Each time, one of the gang [members] will rape the female from behind and others will render assistance and act as lookouts. Then we will have her mouth gagged and hands tied before flashing [leaving] together. That'll be great! This modus operandi has its origin in South Africa, now [it has] spread to the UK. I really hope it can be organised in HK!' Prosecution counsel Eddie Sean Wai-sum told the District Court the two messages Chan posted under his alias 'MasterMind' attracted 102 responses. Half of the respondents showed they were 'disgusted' by Chan's behaviour. One respondent had even suggested organising a 'flash [penis] cutting' gang in retaliation. Among the messages, some respondents said they had reported the matter to police. Mr Sean said Chan had posted a reply to the messages, 'Hum ... reported to the police huh? CATCH ME IF YOU CAN!' Chan was arrested at his home on August 24 after his IP address was traced. Chan told police the invitation was a joke. Mr Sean told the judge that on the day Chan was arrested, he posted another message on GOSSIP to apologise: 'I am purely joking. If you were disgusted by my messages, please accept my deepest apology.' Joanna Wong Wai-chong, who first met Chan online through the 'Fetish for pantyhose' message board, told the court she had found Chan to be a friendly man after they met at gatherings for the group who shared the same interest in pantyhose, but she agreed that the idea of 'Flash Mob Rape' was scary and disgusting. She told the court there was a well-known topic thread on a message board of She.com, 'Let's rob HSBC tomorrow', in 2002 to 2003, but it was a joke. She said she did not believe Chan would really organise a gang rape, yet she agreed with Mr Sean that if there were a group of internet users with a common interest in 'raping', the message board would serve as a platform. The hearing before Judge David Lok Kai-hong continues today.
