A man has been convicted of murdering his ex-girlfriend’s father during a “frenzied” knife assault.

Kamar Williams, 34, stabbed 55-year-old bus driver Derek Thomas while the older man was returning home from work in Stoke Newington, north-east London, last July.

At the Old Bailey, it was revealed that Williams had been searching for Thomas’s daughter, Carron. When he couldn’t locate her, he saw the bus driver and exited his van to carry out the violent act.

Hailing from the Isle of Dogs in east London, Williams fled the scene but was apprehended at the Notting Hill Carnival. He was captured after crashing a rented BMW and attempting to escape on foot while being chased by police.

Prosecutor Anthony Orchard KC informed the jury that on the evening of the incident, 30 July, Ms. Thomas had received threatening and abusive messages from Williams.

She had reached out to the police twice before her father was assaulted, the court was told.

Williams went to the home of Mr. Thomas in search of either him or his daughter, but they were absent.

As he drove away in his van, he noticed Mr. Thomas walking home near Stoke Newington Common around 11:00 PM BST.

Stopping abruptly in the street, Williams exited his vehicle and stabbed Mr. Thomas.

Mr. Orchard described the attack, stating: “Mr. Thomas was struck by the knife five times in various locations in what you may consider to be a frenzied assault.”

During his testimony, Williams asserted that he acted in self-defense after the victim drew a knife.

He stated that he took the weapon from Mr. Thomas and used it against him, claiming he only intended to have a conversation with the bus driver regarding Ms. Thomas.

The jury unanimously convicted Williams of murder and, by an 11-to-one vote, found him guilty of possessing a bladed article.

The verdicts came after nearly 18 hours of deliberation.

Judge Angela Rafferty KC scheduled the sentencing for Friday, 18 July.
