A teenager who led police on a shocking 100mph car chase stormed out of court after being asked to move his hand from his face.

The 17-year-old, who cannot be named due to his age, stood up and declared: 鈥淚 can鈥檛 be a**** with this鈥?before walking out of the room and running from Liverpool Youth Court, in Derby Square.

The boy, from Norris Green, was in the process of being sentenced after pleading guilty to dangerous driving, possession of cannabis and driving with no licence or insurance.

But when the presiding magistrate told him to stop leaning on his hand while sat in court ?asking 鈥淚s your head falling off??- the defendant snapped.

His defence solicitor, Clare Fletcher, and his dad attempted to persuade him to remain but the teenager refused and ran, turning his mobile phone off.

Alison Clarkson, prosecuting, told the court the defendant was arrested after speeding away from a police patrol car in Sedgemoor Road, Norris Green, on December 29 last year.

She said: 鈥淭he vehicle concerned was a Volvo S60. It currently has no registered keeper and in fact is believed by police officers to be a pool vehicle shared between several people.

鈥淛ust after midday an officer on patrol saw the vehicle, which was on false plates, and realised there was something wrong. He saw four young males in the vehicle and decided he was going to stop it.?/p>

The court heard that as the officer approached the Volvo sped off, reaching speeds of 100mph.

Footage from a dashboard camera in the police vehicle was played to the court, showing the car speeding down narrow residential streets before accelerating rapidly along Queens Drive.

The teenager was shown speeding through three sets of red traffic lights, at speeds of up to 75mph, and crossing a raised concrete central reservation.

Ms Clarkson said the kerb deflated all four of the Volvo鈥檚 tyres, but still the teenager continued trying to evade police.

The Volvo was stopped on Barlow Lane, when the pursuing officer saw an opportunity to pull alongside it and force the defendant into a wall.

The other occupants fled but the teenager was arrested at the scene, and later found to be in possession of a small amount of cannabis.

Ms Fletcher, speaking before her client fled court, said he had offered 鈥渓ittle explanation鈥?for the incident.

She said: 鈥淲hat happened when the officer put his blue lights on was completely impulsive behaviour, he didn鈥檛 know what to do. There were others in the car with him; who knows what was going on in the car that day.?/p>

The court heard he had no previous convictions and Ms Fletcher suggested the Youth Offending Service could help address his thinking skills and mental health issues.

She said: 鈥淗e knows this was only a split second away from being a tragic incident, he knows just how close he came to that.?/p>

But as magistrates began asking about how he 鈥渇illed his days,?the teenager lost control.

The court case was adjourned for around an hour, but the defendant failed to return and a warrant was issued for his arrest.
