A teenage boy has been arrested following a police pursuit in a stolen car overnight.
At around 2am Police passed a local service station where the youth was seen filling up a car with petrol.
After spotting the patrol, the youth jumped in the car abruptly and drove off without paying for the fuel.
Police checks on the grey Mazda sedan revealed it had been stolen from Seaton on Monday.

Patrols were able to set up road spikes on the Lincoln Highway, puncturing two tyres of the Mazda.
After continuing for a short distance the youth ran from the car, but was located by police cordon nearby.
The 17-year-old boy from Seaton has been arrested and charged with illegal use, engage in a police pursuit, theft and driving while disqualified.
He has been refused police bail and will appear in the Port Augusta Youth Court later today.
There were no injuries and no damage to any vehicles other than the two tyres spiked by the police patrol.
