The director of child and family services is to return to work after an investigation cleared him of misconduct.

The Ministry of Legal Affairs said yesterday that Alfred Maybury would be back in the job on Monday after five months.

A spokeswoman for legal affairs said Mr Maybury was put on paid “administrative leave” after “allegations from an external party stated that Mr Maybury had not performed his role in accordance with the ministry’s policies and procedures as they relate to the care and safety of children in residential treatment services”.

It was also alleged that he had not followed financial instructions.

The spokeswoman said: “The investigation involved a series of interviews with staff members, a detailed review of the department’s practices and procedures, and a review of the financial activities within the department.”

She added: “These claims levelled against the director were not substantiated.”

But the spokeswoman said the review had uncovered “weaknesses in some of the operations” at residential treatment services, which were now being corrected.

She added: “Steps will always be taken to ensure that the care, welfare and wellbeing of the children is addressed with sensitivity and respect.”

The investigation was launched after allegations that Mr Maybury failed to follow up on complaints of mistreatment of children in care by child and family services staff.
