A driver who ran over a knifeman in an attempt to stop him from stabbing his ex-wife to death in the middle of a street has pleaded with police to drop their murder investigation.

The 26-year-old motorist, identified by his lawyers only as Abraham, said he was being treated as a criminal despite "just wanting to stop him from hurting anybody further"

He was driving to work on Monday morning when he witnessed Leon McCaskre, 41, attacking 43-year-old Yasmin Chkaifi in front of horrified onlookers just metres from her home in Maida Vale, west London.

Abraham, who described himself as a Muslim and family man, said his "instant thought" was to protect the mother of two as he drove his blue Renault Clio towards McCaskre in a bid to stop him.

But Chkaifi could not be saved, and both she and McCaskre died of their injuries at the scene in Chippenham Road.

It has since emerged that the knifeman, who also went by the name McCaskie, was wanted by police after failing to turn up to court just weeks earlier over allegations that he had breached a stalking order by approaching Chkaifi in July 2021.

Police arrested Abraham at the scene on suspicion of murder, but later released him on bail and said he had been fully cooperative with their investigation.

Chkaifi's family praised the driver as "our hero" and suggested he should receive an honour from the Queen – while 23,000 people have signed an online petition calling for the investigation into his actions to be dropped.

In a statement released through his lawyer, Mohammed Akunjee, Abraham said it was never his intention to harm anyone as he called on the Metropolitan Police to de-arrest him.

He said: "I witnessed a man repeatedly stabbing a defenceless woman on the pavement a short distance in front of my car. Members of the public were attempting to intervene.

"The attacker was wielding a knife and was threatening those brave citizens too.

"My instant thought was to protect the woman who had been stabbed and the public who were also being threatened.

"The vehicles ahead of me moved off, which gave me the opportunity to intervene. I drove my vehicle towards the attacker in order to get him away from the woman he was attacking.

"I did not intend to harm the attacker, I only intended to protect those being attacked."

Abraham said he and other passers-by tried unsuccessfully to lift the car away from McCaskre to give him first aid after being unable to reverse the vehicle.

"I am deeply sorry that the man I tried to stop from attacking other people has died, he said. "It was never my intention to harm him, I just wanted to stop him from hurting anybody further."

A friend of Chkaifi has revealed that the mother of two expressed fear that her ex-husband might kill her almost two years before her death.

Her family previously described McCaskre as a "demon", while a childhood friend told The Independent that Chkaifi had had a panic alarm installed in her home.
