A public inquiry in London is continuing to hear evidence into the killings of Barnaby Webber, Grace O'Malley-Kumar and Ian Coates by Valdo Calocane in Nottingham on 13 June 2023
Calocane's former flatmate - named only as Sebastian - has given evidence to the Nottingham Inquiry
He says he reported a "violent" incident - in which Calocane grabbed him and pushed him against a wall - to the police
Earlier on Tuesday, the inquiry heard Calocane visited the headquarters of MI5 in 2021, and asked to be arrested
Bodycam footage of the interaction outside MI5 headquarters was shown to the inquiry earlier. A Met Police superintendent was also questioned over contact with Calocane

The inquiry has heard that an intelligence report from the 31 May 2021 incident at Thames House in London was sent to Nottinghamshire Police.
The report, which was emailed by the Met Police on 1 June 2021, stated that Calocane was spoken to by the police, but was "calm and compliant", before being allowed to leave the area.
It was recorded by the Met Police that Calocane appeared "calm and collected" when officers attended the MI5 headquarters at Thames House.
When asked if visits of a similar nature were common, PC Foster said: "It's not infrequent it does actually occur, whether it is outside Thames House or whether it's actually outside other diplomatic or places of interest.
"It's semi-regular that somebody would wish to pass information on to intel services."
Calocane told Foster it was his "first time" visiting a venue of this kind.
When asked if he had been arrested before, Calocane said he had been.

Foster asked Calocane to keep his hands out of his pockets while speaking to him.
When asked what his plans were when it was established he could not speak to anyone, Calocane said "go home".
The inquiry heard Calocane had booked an Uber to take him home.

Finally, one of Calocane's former roommates, who was involved in two incidents with the triple killer in 2021, is expected to give evidence.
