A “boy-racer” who killed a student just a few months after boasting he had dodged a driving ban for knocking down another pedestrian has been jailed for more than six years.

Abdul Fatah Sujac, 22, was swerving in and out of traffic at speed in a BMW sports car when he hit 19-year-old Laura Keyes as she crossed the road.

Ms Keyes, a student of musical theatre at Trinity Laban conservatoire in Greenwich, was celebrating the end of term when she died on November 30 last year.

It has emerged Sujac seriously injured another pedestrian outside Westfield shopping centre in Stratford in February last year, but was only given a fine and nine points by Thames magistrates after admitting careless driving.

After escaping a ban Sujac sent a bragging video to friends on WhatsApp, captioned: “Nine points ain’t stopping me from driving.”

Police found videos on his phone showing him racing through London, chasing an ambulance, and boasting of reaching 146mph.

Today Ms Keyes’s family said they were “shocked and broken” to learn of his past.

At Southwark crown court Sujac, of Stratford, admitted causing death by dangerous driving.

When he hit Ms Keyes, at the junction of Creek Road and Deptford Church Street, he had been doing up to 68mph in a 30mph zone.

Prosecutor Harpreet Sandhu said his phone had “footage of [him] driving at excessive speeds and seemingly revelling in doing so, undertaking and overtaking and driving on the wrong side.”

Snapchat from August 22 last year said: “ABDUL ripping the road 146mph.”

Judge Deborah Taylor sentenced him to six years and three months in jail. He is banned from driving for five years and must pass an extended test to regain his licence.

Patrick Maguire of the family’s law firm Slater and Gordon called for a review of the “woefully inadequate” sentencing guidelines in such cases.

Amee Patel, a Senior Crown Prosecutor in the London homicide unit, said: “This was a terrible and avoidable death. Abdul Sujac had a cavalier attitude to driving and he now will have to face up to the consequences of his deliberate decision to drive dangerously.”
