"Ok miss, I'll check and make sure you are the cleanskin you are claiming to be ha ha."

That is what NSW Police Constable Vincent John Wendelin, 35, texted to a woman, named Katy, whom he had met on the online dating site eHarmony, on January 27, 2016.

Later, Wendelin decided to look up the record of his female friend using a police database system called COPS (Computerised Operation Policing System) while he was at work at Waverley police station.

He then sent another text on January 28, 2016.

"I noticed that when driving you occasionally feel the need for speed! ha ha! yeah I saw a few DV events but I didn't open them up and look at them, that's your private and personal stuff," he said.
