A prominent entertainment industry businessman with triad connections is believed to have made threats against two outspoken radio show hosts before they quit. Sources close to Albert Cheng King-hon and Raymond Wong Yuk-man yesterday confirmed reports that the businessman, who has a criminal record and has been linked to violence, was sent by a senior mainland security bureau official. The businessman told the pair a Ministry of State Security official was unhappy about what they were doing on their programme, Teacup in a Storm, according to the report in Spike magazine. He also said the official wanted them to leave Hong Kong for a while, and that they could contact him for lost wages. Cheng went off the air in May after three men splashed red paint at the office of his trading company. Wong followed suit two weeks later after a similar threat was made at a restaurant he partly owned. Both men have fled overseas and could not be reached for comments. The magazine report also said Cheng and Wong had given verbal reports to the police, detailing the threat and the names of the businessman and official. However, Police Commissioner Dick Lee Ming-kwai complained that the men did not give enough information to investigators. In response to the new claims, a police spokesman said: 'We are very concerned about the case. We will look into every piece of evidence and information provided by Mr Cheng and Mr Wong. The investigation is still ongoing so it would not be appropriate for us to make further comments.' Cheng's substitute on the show, Allen Lee Peng-fei, quit the post the same month his predecessors left. But it was not likely the pressure on him came from the same source, the report said. Mr Lee appeared in a Legislative Council meeting to explain his reasons for quitting both the show and the National People's Congress. Both Cheng and Wong declined an invitation from legislators to appear at a hearing. The current host of Teacup in a Storm, Leung Man-tao, said about a dozen local businessmen had reportedly gone to Beijing to claim responsibility for the departure of Cheng and Wong, as a way to impress the officials there. While he declined to name the individuals, he said: 'I think that is very funny.'
