A senior diplomat who ran a red light in Wellington was caught in the act by an off-duty police officer - Police Commissioner Peter Marshall.
Mr Marshall described the incident in his weekly blog, saying he saw the offence when he was off duty in Wellington one evening.
"With due diligence I recorded the time, date and place and reported the matter. I was surprised weeks later to hear from a member of the DPS [Diplomatic Protection Service] that the driver was a senior diplomat who had immediately paid the infringement fee.
"We police without fear or favour - from constable to commissioner," Mr Marshall said.
He did not name the diplomat.
