Man Jailed for Manslaughter of Paul Mason After Brutal Westminster Attack
Steven Murdoch Allan, 35, from Eversley, Hampshire, has been sentenced to three years and nine months in prison for the manslaughter of Paul Mason. The sentence was handed down at the Old Bailey on Thursday, 20 April.
Allan had already pleaded guilty to manslaughter and was cleared of murder on 2 February. The attack left Paul Mason with severe injuries, which led to his death six months later.
Deadly Blow in Cambridge Circus
The horror began on the evening of 15 December 2020, when police were called to Cambridge Circus, London W1, after reports of a man found unconscious. Paramedics discovered 51-year-old Paul Mason with a serious head injury. He was rushed to hospital in critical condition.
Detectives, led by Detective Chief Inspector Wayne Jolley from the Met’s Specialist Crime Command, launched an investigation. CCTV showed the suspect punching Mr Mason in an unprovoked attack. Allan turned himself in on 17 December and was charged with grievous bodily harm, though this later escalated to murder after Paul’s death.
Family Speak Out: A Life Shattered by Violence
“We are immensely disappointed that the jury did not all see the intent to cause serious harm that most people who saw the CCTV concluded. We really hoped he would get a life sentence, but at least he will be imprisoned for killing Paul and we can start to move forward a little,” said a family spokesperson.
“Words cannot express how traumatised we were when told about the senseless attack on Paul, simply making his way home from an evening out. Due to COVID restrictions, Paul’s parents could only say goodbye in full protective gear before he spent months in a coma. No parent should have to watch a loved one slowly die after such a brutal act.”
“Paul was a kind, gentle soul who never harmed anyone. He was deeply loved and respected as an international banker and community supporter. He took on challenges like the Royal Parks half marathon and climbing Mount Kilimanjaro to raise money for charity. His death leaves a massive void.”
“We thank the brave nurses who intervened after the attack, the NHS staff who fought to save him, and the police for bringing Allan to justice. Violence like this must never be tolerated.”
Detective Chief Inspector Jolley Issues Warning
Detective Chief Inspector Wayne Jolley said: “Paul Mason’s death tragically shows the consequences of violence. Even without murderous intent, a single punch can be fatal.”
“His family has endured unimaginable pain and acted with dignity throughout the trial. Our thoughts are with them today.”
Remembering Paul Mason’s Legacy
Paul Mason was not just a victim — he was a beloved son, brother, uncle, and a committed charity supporter. The Lyme Regis Museum will soon host a memorial artwork funded by friends to honour his dedication and kindness.
His family vows to keep his memory alive, remembering him for the joy he brought — not the savage violence that ended his life.
