A police officer accused of perverting the course of justice in connection with an earlier vice trial has been identified in court by the sound of his laugh on a tape recording.
Barrister Ken Ng Kin-man, a prosecutor in the earlier case, told District Court he believed the man heard laughing on the tape was police officer Chow Chi-pang.
Chow is alleged to have discussed the fabrication of evidence with fellow officer Yeung Ka-ho, who was about to testify in a 2007 trial involving the operators of a sauna parlour accused of offering sex services.
Ng identified the other man heard on the tape as Yeung. The tapes led to the acquittal of all nine defendants accused, in the earlier trial, of operating a vice establishment.
On the tape, the man said to be Chow can be heard saying: 'I wrote 'f*** your mother' on the notebook. [Sound of laughter.] I was so happy at that time. I bet he would not raise his hand and complain to the judge saying I wrote 'f*** your mother',' the man said, referring to a defence lawyer he called Nick Lau.
The target of his foul words was Nicholas Lau Yiu-kan, a lawyer who had cross-examined Yeung in another trial, Ng told the court.
Ng said Chow wrote the message out of anger after Lau filed a complaint against him, for peeking at his documents.
Chow, 35, and Yeung, 33, have been charged with perverting the course of justice and misconduct. Their alleged conversations were recorded by the wife of one of the defendants in the earlier trial, and led the court to acquit all defendants as it held the prosecution witnesses were unreliable.
In the recordings, two men, allegedly Chow and Yeung, discussed how Yeung could make up evidence and keep his statements consistent.
The trial continues.
