Nottingham attacks families not told 'stalker' had violent past
Barnaby Webber, Grace O'Malley-Kumar and Ian Coates were all killed by Valdo Calocane in a spate of attacks in Nottingham on 13 June 2023
Families of the Nottingham attacks victims said police did not tell them a man who had taken an interest in them had a history of violence when he attempted to visit them.
Barnaby Webber, Grace O'Malley-Kumar and Ian Coates were fatally stabbed by Valdo Calocane, who had been diagnosed with paranoid schizophrenia in 2020, on 13 June 2023. He tried to kill three others.
Grace's father, Dr Sanjoy Kumar, said he was told in 2025 that a man had visited his GP surgery in London. Emma Webber, Barnaby's mother, said he had also travelled to Somerset, but neither were informed of the man's history of mental ill health.
Nottinghamshire Police said it had received a complaint and referred the matter to the Independent Office for Police Conduct (IOPC).
The IOPC confirmed it had received a referral of a complaint from Nottinghamshire Police in relation to information the force allegedly withheld from the families of Calocane's victims about a potential witness who had tried to contact them.
Kumar told the BBC he was informed by Nottinghamshire Police in 2025 that a man from Nottingham, who had taken an interest in his family and the Webber family, had visited his surgery in London.
He said police gave little to no details about the man, with no mention of his past mental health history.
"They [the police officers] said it was a very low brow thing. There was no assessment of risk to me or my family," he added.
Kumar said it was only recently, as a result of ongoing investigations into Nottinghamshire Police, in relation to the attacks, that he was informed of further details about the man by the IOPC.
