The Securities and Futures Commission has moved to liquidate Forluxe Securities and its finance arm as owner James Mui Kwong-nok remains at large in connection with an alleged fraud.
Police are understood to have drawn close to Mr Mui's whereabouts and are also believed to have widened their search to include two other Forluxe directors believed to be Mr Mui's brothers.
Mr Mui went missing last Saturday, leaving his wife hospitalised following complications stemming from childbirth.
Police are understood to be keen to interview his wife, who is a director in Forluxe's money lending arm, Forluxe Finance, once she has recovered.
The SFC yesterday launched a winding-up petition in the high court and placed a restriction notice on the company's assets which freezes shares owned by the brokerage's 630 clients.
Provisional liquidators are expected to be appointed today.
