Yes technically but you will not likely find any police agency to do anything. They will tell you because you gave the person the card, it is a civil matter. Maybe not, but that is what usually happens. They would ask you why you gave someone the card if you didn't expect that person to use the card. Your answer isn't going to convince a jury either. No prosecutor is going to waste his or her time. It is a civil matter.

You can report the card lost and do a chargeback on the transactions. The card will be cancelled and they will issue you a new card. You should have done that IMMEDIATELY. The signatures of the transactions are not likely to match yours, so you are home free. The credit card company is not going to do anything criminal about it. The card company also cares much more about their customer than the mechant. The merchant is the one that gets screwed almost all the time.

In the alternative you can pay the transactions and sue your friend. Lots of luck collecting there.
