We recently had several hundred pounds stolen from our office safe, which only five people have access to. Unfortunately, there's very little evidence to enable us to identify who stole the money.
We carried out a brief internal investigation regarding the theft. We treated all employees equally, asking them the same questions in the same manner. One employee has acted quite badly to the investigation, but without hard evidence, we haven't been able to directly accuse anyone of the theft.
However, said employee directly accused me (the employer) of stealing my own money in an attempt to frame him because he's looking for another job (which he disclosed after the theft). The accusation was witnessed by someone else too. Do I have an disciplinary recourse for the false accusation?
