Someone has made a false statement to police about me

What happens when a statement is made to police weeks after the alledged incident occured of assault,threats and intimidation that are not true,and the accused is required to attend court for the matter charged with common assault and two sequences of intimidation?The accused(person A) has a prior criminal conviction for common assault while on parole which resulted in a 6 month prison sentance.Was let out on parole after three months.Has kept out of trouble and has moved on with his life for the better,getting engaged and having his first child and being a positive male role model/stepdad to his fiances other children.
The accused alledgedly stepped in to stop a female(person C)being assaulted by her then boyfriend(person B)No statements were made to police at the time of alledges incident.
This was when person A was still technically on parole/good behaviour bond.
Person B,has made a statement to police weeks after the alledged incident,citing assault and threatning and intimidating behaviour.PersonC didnt make a statement at the same time as person B.
Person C made a statement approximately three weeks after person B.
The accused has only just been informed and served papers to attend court for the matter in two weeks time.
The accused has denied what both person B and C have stated that happend and that their statements are not true in relation to what happened.
The accused is worried that the alledged victims are lying on their statements to get in him to trouble as they parted ways on bad terms and know person A has a prior conviction for the above.
Person B has sent a text message to the accused several months ago telling him that he can make sure he doesnt see his newborn son for a very long time.This was months after the alledged incident.
Person B was hospitalised for mental health reasons one week prior to the alledged incident.
Person B also has pictures on his Facebook profile holding an axe with very inappropriate comments that do hint to mental instability.What are the chances of being given a prison sentance?
How should person A handle this matter in court if he strongly denies any wrongdoing and the statements are made up of lies just to be vindictive and get him in trouble?
Person A is reluctant to make his own statement as they are scared their prior criminal history is going to make them look gulity right off the bat.That does not help the situation i realise but i can understand why they are hesitant to do so.I also have text messages from the male accusing me of assault saying that he can make sure i dont see my baby son for a very long time.He was eight weeks old when that comment was made which was approximately three months after the alledged assault

Hi,the only thing in writing about this matter is the court summons that i was only given one week ago.

I

I also just realised that the first statement was given November 2018 but gives the date for the second statement as December 2019 which hasn’t even been yet

Thankyou

I have no parenting matters in relation to the current charges.I am in a relationship with the mother of my son that was mentioned in the threatening text message.Neither alleged victim is a parent or even blood relative of my sonWould the threat in regards ***** ***** son fall under family court if I wished to pursue the threat?
