Hi Sharki,
Tell your friend to go to her local Police Station.
Once there she has a few options.
If she just wants the offensive contact recording, she can ask for them to note that the contact is happening on their computer system.
She could also have the fella verbally warned by an Officer who should then record this conversation in their notebook. An intial verbal warning from the Police sometimes has the desired effect without having to make official complaints and statements.
Your friend can also make a written statement and the ex BF could be officially warned under the harrassment act. A record of this will then be kept on the PNC incase of any future problems. Once warned, any further communication by themselves of a third party should result in his arrest.
On the information you’ve given, it could be possible that he could be arrested straight away as it seems that he has entered into a ‘course of conduct.’ Your friend would have to make a written statement about this and he could then be arrested and interviewed on tape.
I would suggest that an initial verbal warning from a Police Officer might be the best response at this time. She would not need to make an statement for this to happen, but the Police would record the full facts. She could then step it up if there was any further contact. More often than not, this verbal warning works.
I would certainly not delete any texts received and I would also tell her to call her phone provider and speak to their appropriate dept.
Also if she does contact the Police, tell her to get a job / log number from them as her phone provider will probably want it and it’s also handy for her own reference.
