Who dobbed Greg in?

The Herald reports:

Labour MP and former police union boss Greg O’Connor has been hit with a $150 fine and 20 demerit points after a member of the public photographed him driving on the wrong side of the road.
It is embarrassing for O’Connor, who was the longest-serving president of the Police Association before he became the MP for Ohariu in 2017.
A member of the public reported O’Connor’s car to police as it travelled through Central Otago on Wednesday last week.
Police failed to locate O’Connor’s vehicle that night, but have since spoken to O’Connor.

“Following further inquiries, the driver of a vehicle which was reported to police on 9 January on SH6 near Queenstown will be issued with an infringement notice for ‘failing to keep left’,” a spokesperson for police said.
“The penalty is a $150 fine and 20 demerit points. Police would like to thank any member of the public who helps us keep our roads safe.”
Last week O’Connor said he had no memory of driving in a way that would warrant police attention, and he repeated that when contacted by the Herald yesterday.
But he had been shown photographs of him crossing the centreline.

I don’t think the infringement is a big thing. Few of us drive perfectly.

What I find interesting is the fact this story got out to the media. It looks like someone in the Police leaked it to the media. As Greg is a former head of the police union, this raises interesting possibilities about motives.
