A 22-year-old man found guilty of killing a Doncaster teacher with a single, 'haymaker' punch was sentenced to more than a decade in prison at Sheffield Crown Court just a few moments ago.
Justice Holgate handed Blue Horrobin of Highfield Road, Askern an 11-year sentence, including a three year extension, after he was found guilty of one count of manslaughter last month.
Horrobin was given the three year extension to his sentence, after Justice Holgate deemed he posed a 'high risk of serious harm' to the public, following the unprovoked attack on 24-year-old Lewis Siddall on August 13, 2015
The extension was also awarded due to behaviour exhibited with Horrobin's previous convictions, one of which saw the former bookmaker fracture a man's cheek bone in three places during an unprovoked attack.
Horrobin, who will not be eligible for parole until he has served at least two-thirds of his sentence, remained silent as he was sent to prison.
A woman in the public gallery sobbed, as Horrobin was taken away to begin his sentence.
It took jurors just 90 minutes to return a unanimous verdict on January 20, following a two week trial at Sheffield Crown Court.
The unprovoked attack took place in the VDKA bar in the town centre as Mr Siddall was out with a group of friends from work on August 13, 2015.
He was found dead in his bed by his mother at around 5am the following morning. The brain fracture caused by a single punch from Horrobin had proved fatal.
Speaking after the verdict Detective Chief Inspector Steve Handley, who led the investigation, said: “Lewis was killed as the result of an unprovoked and senseless act of violence when he was simply out enjoying himself with some friends.
"This was an avoidable death and shows the devastating effect one punch can have on the lives of the victim, their family and friends.
“This could have been entirely avoided; had Horrobin made a different decision not to lash out with his fists, Lewis would still be alive and well today.
“This was a senseless act that robbed a popular young man of his life, and has robbed a loving family of someone they loved so dearly. No prison sentence will bring Lewis back and they will undoubtedly feel a sense of great loss, sadness and anger for the rest of their lives.
I hope that today’s outcome, now that someone has been held to account for what happened, will give them at least some comfort to begin to heal.”
