Tiffany Treanor-Johnson was jailed for more than ten years after killing music student Harry Webb while speeding at 53mph in a 20mph zone while inhaling nitrous oxide.

Tiffany Treanor-Johnson, 27, was jailed for ten years and nine months on Friday after killing cyclist Harry Webb in Hackney in September 2023. She was driving an Audi at 53mph in a 20mph zone at the junction of Kenworthy Road and Hassett Road when she hit Webb, mounted the pavement and crashed into another car.

Webb was a 27-year-old music student at London College of Contemporary Music. He died days later in hospital from major brain trauma after being seriously injured in the crash. He was later awarded his masters degree posthumously. The court heard that Treanor-Johnson had been inhaling nitrous oxide, a class C drug also known as laughing gas, before the collision.

Snaresbrook Crown Court was told that Treanor-Johnson, of Bramshaw Road, Hackney, drove off after the crash, leaving Webb seriously injured on the side of the road. She initially denied causing death by dangerous driving before changing her plea to guilty in April. Judge Rosa Dean also disqualified her from driving for ten years. Treanor-Johnson appeared upset in the dock as the sentence was read out.
