ALAN Ho, executive director of the Hotel Lisboa in Macau, was being questioned by prosecutors yesterday in connection with an alleged prostitution ring, according to Hong Kong newspaper Mingpao.

Police said Ho, 68, had been apprehended on Sunday along with five workers and 96 women they said were prostitutes, 95 from the Chinese mainland and one from Vietnam.

Police said they received a tip-off in April last year that hotel executives were allowing sex workers to solicit clients at the hotel and had identified Ho as a key figure, the Macau News reported. According to the newspaper, an initial investigation found that Ho had conspired with a security manager, two housekeeping managers and two other employees to make a profit of more than 400 million patacas (US$50 million) since 2013.
