A teenager chased by police as he sped at 120mph along the M62 confessed that he had stolen the vehicle from his mum.

Magistrates heard Zacky Mahmood was followed as he left the motorway and raced though residential streets in Mirfield and Dewsbury at nearly twice the speed limit.

He was finally caught after fleeing his abandoned car and told police: ‘It’s my mum’s car - I just panicked’.

The 19-year-old admitted charges of aggravated vehicle taking with dangerous driving and using a vehicle without insurance.

His ‘terrible’ driving was witnessed by police between 3.40am and 3.55am on July 20, Kirklees magistrates were told.

Alex Bozman, prosecuting, said: “Police officers on duty in an unmarked car were travelling on the eastbound carriageway near junction 24 at Ainley Top.

“They noticed a Honda Stream being driven ahead of them at a speed of 120mph.

“The officer caught up with the vehicle, indicating blue lights at him to stop but he didn’t do so.”

The court heard that Mahmood, of Kingfisher Crescent, Dewsbury, slowed the car to 100mph as he approached junction 25 at Brighouse.

As he exited the motorway at Cooper Bridge he headed along Wakefield Road, exceeding the 40mph speed limit.

The teenager overtook a vehicle on a blind bend and then carried on through Leeds Road in Mirfield.

He drove at 70mph as he passed the Three Nuns pub and continued to drive at nearly twice the speed limit as he continued through residential areas including Stocks Bank Road, Nabb Lane, Wateroyd Lane and Lee Green.

Mahmood went onto a public footpath as he carried on towards Huddersfield Road in Ravensthorpe then North Road and Red Laithes Lane before abandoning his car on Broomer Street.

Mr Bozman said: “Both Mr Mahmood and his passenger ran off from the vehicle but were detained close by. When he was arrested he said: ‘I’m sorry, it’s my mum’s car - I just panicked’.

“Mr Mahmood accepted he’d taken the keys for the vehicle 20 minutes earlier.

“He accepted his driving was terrible and he’d driven dangerously.”

Magistrates ordered a probation report on Mahmood, who had no previous convictions, before sentencing him.
