A cyclist could face up to two years in jail after he was found guilty of wanton and furious driving for his part in a crash which killed a Lewisham mum.

Charlie Alliston, then 18, hit Kim Briggs as she crossed Old Street in east London on February 12 last year.

After the crash he leapt up and yelled at the mortally wounded 44-year-old before she was taken to hospital where she died a week later.

Now 20, Alliston, of Trothy Road in Bermondsey, was cleared of manslaughter today (August 23) but convicted of the lesser offence under the 1861 Offences Against the Person Act,

Prosecutors took the unprecedented step of bringing a manslaughter charge due to the unusually grave circumstances of the case.

Following an Old Bailey trial, jurors took more than 12 hours to reach their verdict, which could see Alliston sentenced to two years in jail.

Alliston was riding a “fixie” - a fixed wheel track bike with no front brake, which is not legal on the road – when he hit Ms Briggs.

As she crossed the capital's Old Street, he twice shouted for her to get out of the way but failed to stop or avoid the head-on collision.

Alliston criticised Mrs Briggs and claimed she was responsible for the crash in a string of posts on social media in the days that followed.

He wrote: "I feel bad due to the seriousness of her injuries but I can put my hands up and say this is not my fault."

“Everyone is quick to judge and help the so-called victim but not the other person in the situation, ie me.

"It all happened so fast and even at a slow speed there was nothing I could do. I just wish people would stop making judgments.

"It's not my fault people either think they are invincible or have zero respect for cyclists."

Crash investigators who studied CCTV of the incident concluded Alliston would have been able to stop and avoid the collision if the bike had been fitted with a front brake.

In a statement read in court, Mr Briggs paid tribute to his "wonderful" wife, with whom he had a daughter aged 11 and a son aged 14.

He said: "She was quick to smile, slow to judge and even slower to anger."

Mr Briggs said the trial had been "gruelling and painful", adding: "Out of this senseless carnage, I shall try to bring change to the law and change to attitudes. Perhaps in this way I can honour my wife."

Judge Wendy Joseph QC ordered a pre-sentence report, making clear she was considering jail.

She said: "I have not seen one iota of remorse from Mr Alliston at all at any stage."

She adjourned sentencing until September 18.

Aisling Hosein, from the CPS, said: “Charlie Alliston chose to cycle at speed through the middle of a city without a front brake.

“He collided with Mrs Briggs and knocked her unconscious, and she died a few days later. He then published messages on social media blaming Mrs Briggs and denying any responsibility for the collision.

“We are grateful for the witnesses who came forward to support this prosecution, and our thoughts go out to Mrs Briggs’ family at this time.”
