“As administrators, we will investigate the circumstances surrounding this transaction and other matters affecting the club but will not be in a position to comment further at this time.
“Our immediate priority is to ensure the club can complete its matches and we will meet with key stakeholders to ensure this can be achieved.
“We understand this will be a shock to fans, staff and the local community.
“The club employs 18 players, six football staff and three club staff, whose roles are secured as we work through the early stages of evaluating the options available to the club. We would invite any interested parties to come forward.” .
