Can they

Greg89

On my Facebook 

I put 'hiring web developer' which I'm looking to by a freelance website.

I haven't yet and this on the side, my normal job is a labour job.

I haven't completed my degree but it says I studied degree X at uni y.

If someone calls the police saying I'm lying or doing something dodgy, I'm not committing a crime.

 Can they arrest me?

If no money has changed hands - then you haven't really done anything wrong.

If you are advertising your services and you are lying then I guess it could be trades description but I don't see what they could arrest you for.

 Quite a bit more than what you are doing but its fraud....

I just stated wanting to hire, I'm not saying I'm a developer. Which would be fraud.

Hiring isn't fraud, I could just want a website developed like an info site on a club.

I haven't lied on CV and not applying for developer jobs.

 I'm confused now are you looking for a job or seeking to employ someone?

Opening post is confusing and wants rephrasing

You can be arrested if the police suspect you of committing a crime, is there a crime that people might have reason to think you might have committed?

Even if you are arrested if there's been no crime then it wont go anywhere. If you've just put on social media that you're looking to hire a web developer I can't think of any reason for any police interest.

So you have stated you want to hire a web developer when you have no real intention of doing so? I am guessing from the second bit that your intent/hope/thoughts are to act as a middleman to win web dev jobs and your freelancer then deliver them.

Cant see where you believe there is fraud? However the questions suggests you may not understand contract law very well. and possibly other things, which may mean you are taking on liabilities that you dont understand.

There are a wide range of reasons why jobs advertised dont result in anyone being appointed, none would be considered fraud.

I am seeking to merely hire a developer, I haven't yet but I will.

I find that a bit of a confusing post. 
It is unclear what you are seeking to do / achieve and what you think would be fraud or a Police matter.
The only thing is, if you are using incorrect tense in how you present yourself then that can be misleading but probably short of fraud, so for the highlighted part of the original post a slight re-phrasing might be more appropriate:
Currently studying X at Uni Y, expecting to Graduate in Summer ZZZZ with forecast A Class Honours.
