The Court of Appeal has refused to change the sentence of Nottingham killer Valdo Calocane.

Calocane was given an indefinite hospital order for the manslaughter of three people in Nottingham last year.

Calocane pleaded guilty to manslaughter by reason of diminished responsibility of Barnaby Webber, Grace O’Malley-Kumar and Ian Coates, and the attempted murder of three others, in a spate of attacks in Nottingham last year.

Speaking at the hearing at the Court of Appeal, Lady Chief Justice Baroness Carr concluded there was "no error" in the sentence given by Justice Turner at Nottingham Crown Court in January.

Three senior judges dismissed the bid earlier today, stating that while Calocane’s offences caused "unimaginable grief" his sentence was not unduly lenient as his paranoid schizophrenia was "the sole identified cause of these crimes."

Baroness Carr said: "It is impossible to read of the circumstances of this offending without the greatest possible sympathy for the victims of these terrible attacks, and their family and friends.

"The victim impact statements paint a graphic picture of the appalling effects of the offender’s conduct.

"Had the offender not suffered the mental condition that he did, the sentencing judge would doubtless have been considering a whole life term."

She added: "But neither the judge nor this court can ignore the medical evidence as to the offender’s condition which led to these dreadful events or the threat to public safety which the offender continues to pose."
