He refused to stop having sex when police asked

The service station attendant could see the pair "kissing passionately", and Mr Tierney said the attendant could hear loud moaning and the woman was "moving in ways that gave the impression the pair was having sexual intercourse".

The attendant called the police, who arrived at 8.30pm, asking the couple to stop.

They did not, and Spratt was not arrested until 27 minutes later.
