"It was in the afternoon and a miserable sort of day anyway.
"He was going through to Patea and we chatted away for most of the trip."
But when he dropped the man off in Patea's main street, Mr Borrows noticed his cellphone was missing.
"I keep it in the centre console of my car so when I saw it wasn't there, I did a U-turn and caught up with this bloke."
Mr Borrows said he and the man had a "short, sharp discussion".
"It was a conversation that was somewhat truncated, with a number of monosyllabic words tossed in," he said.
He eventually found his cellphone a short distance away behind a building and then took the man to the Patea police station.
"There was no one at the station so I rang the Hawera station. But when I didn't raise anyone there I rang 111. I explained it wasn't an emergency but that I was making a citizen's arrest," he said.
The man will appear in court next week.
As for Mr Borrows, you could say it was a case of him limbering up for his role next month when he will be Acting Police Minister, covering for the minister Ann Tolley who is overseas for a couple of weeks.
