DBS

The DBS did not tell the BBC why he was allowed to work with children in 2021 and then barred in 2023, as it does not comment on individual cases.

DBS checks are issued directly to individuals, not the organisation requesting them, but a DBS spokesperson said it was the responsibility of employers to review employees' certificates.

They said after the incident, it reviewed the DBS checks of all of its employees working with children in Yorkshire and "no further issues" were identified.

Asked if it was an individual's responsibility to inform an employer if their DBS said they were barred, she said: "I think it's absolutely critical that the employer gets a copy of that document so that together they can make the right decision and keep our communities safe, and particularly keep our children and young people safe."

St Giles said its senior management was not aware of the outcome of the most recent DBS check until December 2024, which meant Zaman continued in his role - and had contact with 28 children - after being barred.
