An investigation into a payment made to Prof Sir Ian Diamond has been launched
The Scottish Charity Regulator (OSCR) is probing a six-figure payment made to the former boss of a university.
Professor Sir Ian Diamond announced his plans to retire in 2017.
However, it is understood his 12 month notice period only began in July last year when he had actually left his post.
OSCR confirmed to BBC Scotland that it is investigating the case. This follows the Scottish Funding Council (SFC) stating in June it was reviewing the payment - believed to be in the region of £280,000.
An OSCR spokesman said: "We can confirm that we have an ongoing inquiry.
"In line with our inquiry policy, we cannot comment on an ongoing inquiry as this may prejudice the work of OSCR and the charity."
Esther Roberton, of the University of Aberdeen, said: "As senior governor of the University of Aberdeen I am committed to ensuring proper use of public money.
"The university is cooperating fully with OSCR and SFC regarding the circumstances of the retirement arrangements of the former principal."
