Can a poloice officer legally remove a vehicle you own and reported it stolen from the national stolen database

I'm from Colorado. I own a 99 van (tags and title in my name) recently it was stolen from my home by friends of the family who were staying with me while I was away from the house. I called my local police and reported it stolen gave them all info including there names as well as descriptions of person whom had taking it without permission. The next morning after it was reported I was informed it was put into the vehicle nation wide stolen database. The officer then spoke with neighbors (all of which were friends with who stole it) and they lied saying no it was there's so without even telling us the officer had taken it out of the database. I was not informed of any of this until I found out where the vehicle and person who took it was staying and called. Now police say the only way I could get my vehicle back from the theirs is by going three civil court but van is all in my name. What legal right do I have and are they legally able to do this?
