A talented boxer had taken cannabis and was speeding when he crashed on the M4, an inquest heard.

Mohammed Hashim died in the crash in the early hours of April 7.

The Cardiff 18-year-old’s inquest at Wiltshire and Swindon Coroner’s Court in Salisbury heard he had cannabis in his system and was speeding when his BMW veered from lane two to the nearside lane between junctions 14 and 15 of the motorway.

The car struck the embankment and a motorway barrier before landing on its roof and rolling across the road. The vehicle came to a rest in lane three of the westbound carriageway.

Coroner Ian Singleton recorded the cause of Mr Hashim’s death as road traffic collision.

He said: “Mohammed sustained the injuries which led to his death at the time the vehicle landed on its roof.

“On a balance of probabilities, the vehicle left the road due to a combination of excessive speed, the taking of cannabis and the lack of driving training and the passing of a driving test.”

In a statement released by Wiltshire Police shortly after the crash, Mr Hashim’s family described him as generous and full of energy.

“Mohammed was an inspirational individual with good morals and ethics. He was a giver, a doer and never liked receiving. He was the most generous and thoughtful person anyone could meet,” they said.

“[His] views in life was ‘be kind to everyone, even the unkind ones because paying bad with bad does not equal to good.’ He had the most electrifying smile in the world, he could light up any room he entered.

“Mohammed was an outstanding young individual with great prospects and was always full of energy. It’s sad to see his life cut so short. He will be sadly missed and rest assured forever in our hearts.”

The talented boxer was said to have been ranked second in the world for his age at one point in his fledgling career. He had represented Wales.

Head boxing coach Carl Stephens of Llanedeyrn ABC gym in Cardiff, who taught Mohammed from the age of 10, said: “Mo was just a young man compared to these seasoned boxers but they could not believe the ability he had with his limited experience.

“There were a lot of well-placed people on the boxing circuit who thought Little Mo could have gone right to the top.”

“Mo was like second son to me. He was a likeable, bubbly, smiling young man who everyone loved. It is a tragedy for his family, friends and all the boxing world that such a talent has been lost at such a young age.”
