After being caught by the cops McDonagh can then be seen laughing and asking a passerby for a “ciggie” as he is being arrested.
Just minutes after the savage attack in August last year, arrived outside Bognor Regis station, West , and seized the knife that he’d used in the unprovoked attack.
In footage released by the McDonagh appears to be unbothered as he is arrested.
As someone walks past out of shot, he says: “You haven’t got a ciggie, have you luv?”
He then turns around and can be seen with a broad smile on his face before asking someone else: “You got a ciggie on you, geez?”
McDonagh, 22, and of no fixed address, appeared at Crown Court on Friday 2 January and pleaded guilty to Grievous Bodily Harm (GBH) and two counts of Possession of a Bladed Article.
He was sentenced at the same court on Friday 27 February to four years’ imprisonment.
The court heard that the victim had been at a friend’s flat in the early hours of Tuesday 25 November 2025 when McDonagh showed up and was aggressive to both before falling asleep.
They left the flat to get some food and returned a short time later when McDonagh awoke and was again aggressive.
At around 8.20am in the morning they left the flat again, while McDonagh remained despite having been asked to leave.
McDonagh then appeared from an alleyway before throwing a glass bottle and a kitchen knife at the victim.
He then picked that knife up and chased the victim towards the station with knives in both hands.
CCTV footage shows McDonagh lunging at the victim in the station forecourt, leaving him with a significant slash injury to his right arm.
He continued to attack the victim, knocking him to the floor before he was able to get up and run away.
The victim was rushed to hospital for emergency surgery to the deep wound on his arm.
Detective Constable Christopher May said: “I’m pleased to see McDonagh receive a significant custodial sentence that recognises both the physical and psychological harm he caused to the victim, and the shock and concern he caused to the community.
“Our detectives and forensics officers worked tirelessly to gather vital evidence so that McDonagh could be charged and remanded within 24 hours of the incident, ensuring he was taken off the streets and justice achieved for the victim.
“I’d like to thank them, our partners at Sussex Police, the local authority and the for their incredible hard work and support during our .”
