Voluntary Interview - Has Police officer commited an offence?

[efpom]

A police officer sent a text to the mother of an alleged victim – a child, informing the mother that the police officer intended to request a suspect the police officer named in the message to attend a voluntary interview, “and keep you [the mother] updated.

The mother is a potential witness
Q has the police officer committed an offence by sending that text? If so, what is the offence.
This is real world – Not an exam question!

The police officer shouldn't have referred to the suspect by name, only as the suspect. No doubt the police has that covered in their 'policies and procedures manual'. I suspect it also breaches 'data protection' regulations.

My writing was slightly inaccurate - what I should have clarified is that the child alleged that the person named in the text had commited a criminal offence against the child

In fact, that person, who the police officer named, had not had any contact with the police, until a couple of days later, when the invitation was to attend for a voluntary interview was made, by that police officer, who did, in fact, conduct the interview. |

Further, the mother then published that text message to others potentially involved, including potential witnesses, before the interview occurred.

If a person makes a complaint to the police about a crime being committed against that person, it is pretty obvious that the alleged criminal will be interviewed under caution (whether voluntary or not), so I don't see that the police have committed an offence.
