Hadn't come across English Emma before (literally or metaphorically), but I think this is a little harsh don't you?

Ok he's in public facing role, but unless he used the PNC to get her number he's not done anything "too wrong", I guess it was for breaking a code of ethics or misconduct in public office or similar
Reading from the beginning of the article, it states
"despite claiming he had been searching for massages online".
That reads to me that he stupidly used a computer at work (which all searches are monitored even when not using the PNC).
Also, PC's do get issued with a work mobile phone.
I'm guessing that he may have been on duty at the time of the messages which would be misconduct.
If only he'd been a member here, he'd have known to use a punting phone 
Seeing SPs isn't illegal - he's not broken the law. How did they find out is what I want to know?
The first sentence made me laugh

I did initially think that police officers are allowed to book SP's, but I then did a quick Google search and apparently they are not.
