Knife-wielding robbers acted with "appalling violence" in a savage and frenzied attack on members of the public who tried to stop them.

Tyrone Dean, 24, and Louis Parkinson, 26, had already stabbed one victim in central London when they robbed a second person of his phone in the City in October 2022.

After he called for help, they lashed out at passers by who tried to stop them.

One victim needed more than 50 stitches to his face and another told the court she would "never be the same".

Dean, of Willow Walk, Duckett’s Green, and Parkinson, of Catherall Road, Highbury, were both jailed for 12 years for the attack in October 2022.

At around 9am on October 6, 2022, Dean and Parkinson stole a phone in Fitzrovia, stabbing their first victim, Paul Grange, in the arm before cycling towards the City.

Around 45 minutes later, the duo, who were wearing masks, snatched a phone from their second victim, Nicholas Badger, in Bishopsgate.

Mr Badger shouted out during the theft, alerting passers by who tried to stop the pair from getting away.

Dean and Parkinson then launched a knife attack, stabbing or slashing three of them, with one victim requiring more than 50 stitches to his face.

Alison Sanders, who single-handedly tried to stop Dean from escaping, was stabbed in the arm, resulting in a severed tendon and nerve damage.

Another person who intervened, Henry Carlton-Weedy, needed 52 stitches after he was slashed in the face with a knife, leaving him with a severe scar from the top of his cheekbone to his mouth.

Another man, Vladimiros Konstantinidis, was stabbed twice in the chest and once in the back, causing a collapsed lung, when he tried to stop the thieves.

Mr Konstantinidis said he had been left “in a worse place” after the incident as he had had to spend some of his savings – which had been earmarked for his wedding – when he was forced to take six weeks off work due to his injuries.

Dean, admitted robbery, possession of a knife, assault occasioning actual bodily harm, theft, two counts of wounding, attempting to wound, and possession of cannabis.

Parkinson pleaded guilty to assault occasioning actual bodily harm, possession of a knife, attempting to wound, wounding with intent to do grievous bodily harm, and possession of cannabis.

At Inner London crown court, Judge Benedict Kelleher told the pair: “You acted with appalling violence.

“The incident caused widespread concern and national media coverage. It was a truly shocking example of mindless violence and utter lawlessness.”

Both men were jailed for 12 years on Thursday (August 10). They will have to serve at least two-thirds of their sentences, and will spend an extra five years on licence once released.
