Online radio presenter Wan Yiu-sing was on Friday jailed for two years and eight months by the District Court for sedition and money laundering.
Wan, 54, who is better known as Giggs, earlier pleaded guilty to conspiracy to act with seditious intent and laundering HK$10 million of crime proceeds.
The court heard that the defendant incited people to resist or overthrow the Chinese Communist Party and had advocated Hong Kong independence while presenting an online radio programme over nine months in 2020.
It was also told that Wan raised money for Hongkongers who moved to Taiwan after the 2019 protests.
In sentencing, Judge Adriana Noelle Tse said the media has an influence on the public and the online shows involved in the case were widely circulated at a time when Hong Kong saw sustained serious violence and illegal activities.
She said Wan committing seditious acts under such an atmosphere had clearly worsened the situation, increasing the risk of a breach of the peace.
The judge ordered the defendant to hand over assets worth nearly HK$5 million within the next six months.
