How long until investigations are completed and I get charged or NFA’d?

There is no way to predict this. You are at the mercy of the police who have very limited resources. If youa re very lucky and the false accusation is obvious it may take just a few weeks. However this is rare. The majority of decisions can take months, if not years to complete. It is very important that you look after your mental and physical self in this time. Take a look at our Well-being and support sections to find help during this time.
