The inquiry also heard, according to Nottinghamshire Police policy – in which the charging of a person with a criminal offence who might have a mental health disorder was being considered – the matter should be referred to the Crown Prosecution Service.
That did not happen on this occasion, the inquiry heard.
The force’s policy on dealing with suspects who were mentally unwell also said doctors’ notes should be seen as “opinion”.
It was based on Seedat’s response that Marsden and his sergeant decided not to interview Calocane.
The inquiry heard Calocane had attempted to force entry into another flat at the same complex – where he believed his mother was – in the early hours that day.
None of the officers dealing with either of the incidents on 24 May linked them together. However, at the inquiry, Marsden, said they “should have” been linked.
Calocane was arrested following the first incident but released from custody back to Brook Court later the same day.
Custody notes, which were shown to the hearing, detailed Calocane’s demeanour saying he had been talking about “seeing the devil”.
No further action was taken in relation to the incident in the early hours.
In evidence, Insp Katie Eustace, of Nottinghamshire Police, admitted the incident was not “given the attention it deserved”.
A former neighbour of Calocane’s – named in the inquiry as Liam – who reported the earlier incident, told the inquiry the killer had knocked on his door on numerous occasions.
One one occasion, Calocane told Liam he was trying to help him as Liam had “upset a gang and now they were after [him]”.
Liam told the inquiry on another occasion in 2022, Calocane threatened to rape his partner, but that they decided not to call the police.
The inquiry continues.
