A man has been jailed for life for the murder of a Cambridge student who died, despite the efforts of off-duty doctors who tried to save him.
Chas Corrigan, 22, killed Mohammed Yousef Algasim in Mill Park with a kitchen knife on August 1, 2025.
Mr Algasim, 20, from Saudi Arabia, was in Cambridge on a 10-week placement to study English.
He fled the scene before collapsing nearby.
Despite efforts by three off-duty doctors and paramedics, he died from a severe neck wound at 12.19am.
Mr Algasim’s family said: "This has been a very difficult journey for our family.
"Losing Mohammed has left a deep void in our lives.
"Whilst nothing can bring him back, today’s verdict recognises the seriousness and brutality of how his life was taken."
CCTV footage captured the entire incident, showing Corrigan running from the scene.
He was arrested following a tip-off from a member of the public after a media appeal.
During the trial, Corrigan, of Holbrook Road, Cambridge, admitted carrying the knife but claimed he intended only to scare off potential attackers, not use it.
A jury at Cambridge Crown Court took less than two hours to find him guilty of murder following a two-week trial in March.
He had already pleaded guilty to possession of a knife in a public place.
He was sentenced to life imprisonment with a minimum term of 22 years and six months in prison.
His father, 51-year-old Peter Corrigan of Vinter Terrace, Cambridge, was also sentenced at the same court.
He appeared via video link from HMP Peterborough and received two years in prison after pleading guilty to assisting an offender.
Peter Corrigan was caught on CCTV at 9.04am on August 2 removing his son’s blood-stained jacket from bushes in Vinter Terrace and placing it in a wheelie bin.
He also helped his son avoid arrest by letting him hide at the Holbrook property.
Detective Chief Inspector Dale Mepstead, from the Major Crime Unit, said: "Today’s sentence reflects the seriousness of Chas Corrigan’s actions.
"He chose to arm himself with a knife and carry it in a public place, with devastating consequences.
"Mohammed was a young man with his whole life ahead of him, and his death has had a profound impact on all who knew him.
"Our thoughts continue to be with his family and friends as they come to terms with this tragic loss."
DCI Mepstead said: "I would like to thank members of the public who came forward with information, as well as those who tried so desperately to help Mohammed at the scene.
"Their actions were invaluable to our investigation."
Mr Algasim’s family also expressed their gratitude to all those involved in the case, including Cambridgeshire Police and the prosecution team.
They said: "We thank Cambridgeshire Police for their thorough investigation.
"In particular, we are grateful to Lucy Bright and Charlie Sermon for their steady communication and support.
"We also acknowledge the wider investigation team and those working behind the scenes for their efforts.
"We recognise the Prosecution team, especially Nicholas Hearn and Ruby Shrimpton, for their clear and focused presentation of the case.
"We understand that the legal system here is different from our own, but within the British legal framework, they carried out their responsibilities with professionalism and commitment.
"Finally, we thank the jury for their thorough consideration of the evidence and for reaching a verdict based on the facts presented in court."
