Dozens of people from a group supporting the police staged a protest on Friday outside RTHK’s headquarters in Kowloon Tong, accusing the public broadcaster of smearing the force, spreading hatred, and damaging Hong Kong.
The group calling itself "HK Force of Peace" condemned recent episodes of RTHK’s satirical show Headliner that have made fun of the police, saying the programme is biased and misleading.
The protesters chanting slogans including "RTHK harms Hong Kong" as some waved Chinese flags.
One of the demonstrators, who called himself K, accused the government-run public broadcaster of spreading fake news.
He added that Headliner should be more "mature".
"We come here to protest because this TV channel keeps making fake news. And the actors in this TV programme discriminate against the police force and make funny jokes. It's so childish. They should think, they are adults. They should teach the people how to love each other," he said.
"This is a TV programme of the government. We sponsor them. They use our money, right?"
The protest was the latest in a series against RTHK since the extradition bill crisis erupted last summer.
In a letter to RTHK's staff on Thursday, the Director of Broadcasting Leung Ka-wing had addressed the ongoing row between the station and the police force, saying various government departments should respect each other and understand that they have different roles to play.
Leung had reiterated that Headliner is not a factual programme, saying most people recognise that it doesn't provide news.
