They've issued a statement this afternoon, (Friday 3rd January), saying any alleged issue happened before Mr Abdallah Lemsagam took Latics on.
The words on their website read:
"After a lengthy and detailed investigation regarding the financial conduct of the owners of the club before the acquisition by Mr Abdallah Lemsagam, it has been found necessary to make an official complaint to the Greater Manchester Police.
"The allegations are mainly against those who had dealings with Oldham Council when grant money was allocated to the club towards the building of the North Stand
"We must make it clear that Oldham Council along with other agencies have fully co-operated with the club.
"The FA and the EFL will be advised accordingly."
The stand was renamed 'The Joe Royle stand' after the legendary manager in 2018.
The Oldham Evening Chronicle has contacted Oldham Athletic for a statement and we're waiting for a response.
