The Department of Justice says due to limited available evidence, no further action is warranted regarding video clips posted on a website last October involving Secretary for Development Paul Chan.
The department said the footage appeared to have been edited, but the Police could not obtain any further evidence or assistance from people who took the video or any other relevant people.
After carefully considering the matter, Director of Public Prosecutions Kevin Zervos concluded that no further action is warranted.
In response to media enquiries, Mr Chan said he respects the department's decision, saying he understands public expectations regarding principal officials' conduct and behaviour.
"I shall stay alert at all times and speak and act cautiously. I agree that one should not drive after drinking alcohol and shall be more vigilant in future," he said.
In October, video clips were posted on a website depicting Mr Chan drinking beer at a Jockey Club restaurant with his family, and of Mr Chan's private car being driven on a road which momentarily crossed double white lines.
Mr Chan reported the matter to the Police. After completing their investigation, the Police sought legal advice from the Department of Justice.
To avoid any perception of bias or improper influence, and after satisfying himself that the prosecutions director had no connection with any person involved in the case, the Secretary for Justice delegated to the director the authority to handle the case, including considering whether any prosecution action was warranted.
