Hong Kong’s anti-corruption agency said on Friday 20 people had been arrested suspected of taking bribes to help people apply for early withdrawal of government pension funds with false documents, amid a row over new passports offered by Britain. Hong Kong pension funds have been in the spotlight since the emigration of more than 140,000 Hong Kong people to Britain after 2020 when China imposed a national security law on the former British colony, cracking down on dissent. The authority running the pension scheme then said it would not accept the passport as a valid document for the withdrawal of funds.
