Drink-case cricketer 'trying to rescue cat'
He said he then got in his white Porsche Cayenne and drove towards a branch of Asda when he was pulled over by Pc Steven Denniss, Nottingham magistrates heard.
Pc Denniss told the court he decided to pull Swann over initially because he was driving a high-performance car in an area where there had been a spate of burglaries.
He said when he turned round to pursue the cricketer, Swann initially accelerated before eventually stopping.
Pc Denniss, who had just started his patrol at 3am on April 2, said: "Mr Swann stated he had been out that evening and had come back to find his cat trapped under the floorboards in his house. He had gone to Asda to fetch some screwdrivers to remove some floorboards.
"His speech was slightly slurred but he was compliant. He was slightly upset due to the fact of his cat and what had just happened."
Pc Denniss said Swann then admitted to the officer that he "shouldn't have probably been driving".
The court heard that Swann, who was named England's player of the year in May, was "borderline". A blood test found he had 83mg of alcohol per 100ml of blood. The legal limit is 80mg.
Swann, of West Bridgford, denies one charge of drink driving.
The trial will resume on October 7 to tie in with Swann's cricketing commitments.
