Teenager David Young will spend Christmas behind bars after giving his brother's name when he was stopped driving without insurance.

The 19-year-old, who doesn't have a driving licence, panicked when he was caught behind the wheel of a BMW on the evening of May 28, Swindon Crown Court heard.

Rob Welling, prosecuting, said police pulled over the vehicle on a routine stop and the defendant told them he was Darren Peter Young of Charlotte Square, Trowbridge.

He said that his brother's details were correct except for the date of birth which was a combination of the two men's.

Mr Welling said that Young was told to produce his documents at a police station, but obviously failed to do so.

"The police let him go, he was asked to produce, he didn't and the inevitable happened. A summons was processed in the name of Darren Peter Young and sent to his current address," he said.

"Darren went to the police station and approached the arresting officer who immediately recognised he was not the man he had stopped."

Police later saw the defendant and caught him after a 300m chase through Trowbridge.

When he was interviewed he told police officers that he had panicked because he didn't want to get arrested for not having insurance or a licence.

Mr Welling said that Young had a string of previous convictions for shoplifting, common assault and motoring matters.

At an earlier hearing, the teenager pleaded guilty to perverting the course of justice, driving without insurance and otherwise than in accordance with a driving licence.

Philip Warren, defending, said: "There is no polite way of putting this, this defendant isn't very bright. If he had been he would have realised that you are unlikely to be arrested for driving without insurance as it is far less serious than attempting to pervert the course of justice."

He said Young had only driven a short distance when he was stopped and fortunately his actions had not led to dire consequences for his brother.

Jailing him for three months Judge John McNaught said: "When people are stopped and give false names, the courts almost always send them to prison because it's an attack on the way the system operates."
