It is up to you if you want to go - as in theory, no one can provide any legal advice to you except your lawyer.
But if I were in that situation, I will tell the police that I will choose not to go - unless they are going to arrest me.
Here are my reasons:
1. I can effectively avoid saying anything incriminating myself during the interview.
2. I can effectively estimate where I am at in this case - For example, if the police has enough evidence, they will not ask me for an interview - but they will simply arrest me. So I will be able to tell based on the police's action to know if I am a person of interest or suspect.
3. If I am officially arrested, it is my right to request a lawyer to be presented when I am interviewed. But if you simply go, I can't unless I hired one.
