After his arrest in June last year, Valdo Calocane was charged with three counts of murder and three counts of attempted murder.
But while on remand he was transferred to a high security hospital to be assessed by forensic psychiatrists, who found he couldn’t be tried for murder because of mental illness.
At a Nottingham Crown Court hearing on 28 November, he pleaded not guilty to three counts of murder but guilty to manslaughter.
He admitted the attempted murder of Wayne Birkett, Marcin Gawronski and Sharon Miller whom he attempted to run over while driving a van.
Calocane was then sentenced to a hospital order with restrictions.
Emma Webber, the mother of student Barnaby Webber, who was stabbed to death in the attacks, said “true justice” had not been served.
