The inquiry heard in December 2019, while he was enrolled at The Acorns, he returned to the Range school and attacked another student with a hockey stick – while also carrying a knife in a backpack.
After his arrest his bail conditions meant he could not return to The Acorns until he had a “multi-agency risk assessment”.
Ms Hodson said she had “very significant” concerns about the risk he would pose to other pupils and staff if he returned.
However, she felt resistance from other agencies, and said: “I felt they all took a step back and passed the risk to us, their solution was ‘you’ve got to take him back’.
“The police peeled away, social services said they didn’t think there was a risk, and we were literally left holding the baby.”
She recalled a meeting attended by the specialist Forensic Child and Adolescent Mental Health Service (FCAMHS), designed for youths considered at risk of causing harm to others.
At that meeting FCAMHS nurse John Hicklin made a comment about placing a £5 bet with anyone who could predict what Rudakubana would do next.
Ms Hodson said she felt “ganged up on” in that meeting and like she and her school had been left to deal with the problem on their own.
From January 2021, she said she became concerned Rudakubana’s father was fearful of his son and had “lost control” of him.
The inquiry continues.
