The Broadcasting Authority has advised Commercial Radio to make sure it complies with a code of practice designed to protect people's reputations, following complaints that a radio host used crude and vulgar language.
The 124 complaints surrounded radio programme On a Clear Day, in which host Vincent Wong Wing used 'vulgar and abusive language' against a government information officer when discussing the felling of an old flame tree in Tai O by contractors for the Lands Department.
'Only words such as disgraceful, cheap, shameless, untrustworthy, inferior, substandard, unscrupulous are appropriate to describe you and your department.
'Words like crooked, shameless, contemptible and disgraceful are not sufficient to describe your unscrupulousness,' Wong said in the programme on January 22.
He also said he would post an obituary for the tree on the officer's door during Lunar New Year.
'The way he highlighted the name of the officer concerned; made her the subject of personal abuse and attacks on her character, had gone beyond expression of his views on the issue,' the authority said, adding that Wong 'had not taken special care in his use of language'.
