Later on Tuesday, the inquiry heard from a hostel worker, known as Ivan, who encountered Calocane on the day of the attacks in 2023.
Ivan was working at a 52-room hostel, Seely Hirst House in Nottingham, when Calocane approached the building and tried to prise open one of the windows.
Ivan told the inquiry he saw a man on CCTV and went outside.
Via a Slovakian interpreter, he said: “I spotted this person who was trying to open the window and I, as a person who often deals with trespassers who are not residents, I assumed it was someone in need of help, a homeless person looking for somewhere to sleep.”
The inquiry heard Calocane had asked “what sort of building it was”, to which Ivan responded it was hostel, and told him to return later, at 09:00, when social workers would be there.
He said: “I tried to approach his heart. I offered him help. He leant against the railings and was looking into my face with an intense look.
“No blinking, no smiling, he didn’t seem nervous at all.”
Ivan said he did not think to call the police and asked Calocane to leave the garden of the hostel.
CCTV showed Calocane walked away from Ivan, but then started to approach another window, which was slammed shut in front of Calocane.
The inquiry heard Calocane was punched by a resident while being denied entry to the hostel and eventually left.
By that time Calocane had already killed Barnaby and Grace, and shortly after, stabbed to death Ian Coates before driving his van into the city centre and striking pedestrian Wayne Birkett, Sharon Miller and Marcin Gawronski.
The inquiry continues.
