Can I move away with my son without the father's consent?

You did not provide any of the relevant information. It sounds like you were not married to the father. If so, did the father ever establish his legal paternity. If not, you can do whatever you want. If he did, you need to give notice per the relocation statute and provide a basis for why moving would be better for your son than staying close to the father (e.g. a better job, family support nearby, better schools, etc). Are there legal restrictions on the father as a result of the police intervention? If so, a court is more likely to grant a request to move. You should consult with a lawyer who can look at the whole situation and give you advice.
