Can police find me from private IP address or public?

My friends and i made a fake account and impersonated someone for only two days. We didn't threaten anyone. The person filed a police report on me and its really scary. We changed my IP address and networking system of the iPhone. Can police still find us and how long does it take?

Added (1). We didn't do anything that bad we just said a few mean things

Added (2). It's really scary though

There's no way to dodge the bullet if your on the internet.

The short answer is yes. The NSA has the communication intercept capability to connect the IP address and match any cellphones that were in close proximity to the computer at the time of the crime. Thus establishing a link between the phone owner and the computer in question. Hope you didn't do a bad thing.

If they are looking for you, it could be a week depending on how urgent it is to find you.

Oh Yeah they can find you by via your unique internet provider IP Address. The IP Address you change is sort of temporary, there's another special IP address they can get from Cable company. Am assuming your is Cable modem.

I may be wrong up above its been long time ago since I study computers.

the way you said tell me you don't have special box that Hacker use to hide their true IP address and they create a ghost network ip address nodes. Of course those Box are illegal and are created by Hacker them self or one of their Hacker buddy.
