The government says it strongly condemns unfounded malicious attacks online, after a court issued an order to confiscate the alleged crime proceeds of self-exiled national security suspect, Ted Hui.

The Court of First Instance issued the confiscation order on Monday upon application by the Department of Justice.

In a statement overnight, a government spokesman accused Hui of committing numerous crimes, including conspiring with foreign politicians in 2020 to forge documents and deceive the court, in order to jump bail and abscond overseas.

"Before and after Hui Chi-fung absconded from Hong Kong, he transferred nearly $2.5 million Hong Kong dollars in personal assets as gifts to his mother and wife," the spokesman said.

The government spokesman said such a gift made within six years from the date of prosecution may be regarded as the defendant's property, and confiscated under the law.

The statement said it was common practice to confiscate crime proceeds, and denied that private property could be 'confiscated at any time' or 'arbitrarily', as such orders must comply with strict conditions.

These include that the court must be satisfied the absconded defendant could have been convicted of the offence and whether they benefited from the offence.
