I live in Calgary Alberta, I recently lent my van to my roommate. I did not ask him what he needed it for. I was contacted later that evening by police who asked if I knew where my van was, which I didn't. I filled out a statement for the cops stating my roommate borrowed my van. Turns out he filled jerrycans at a gas station with $200 worth of fuel and attempted to use a stolen gas card then fled without paying. I've explained to police that my roommate hasn't been back and only just got my vehicle back. The cops asked me if I knew the implications I could face , are they bluffing or could I be in trouble for this at all? Please let me know what if any repercussions could be against me. Thanks.
