Neighbor Cut my Burning Bushes?

Is there anything I can do about a neighbor that whacked down half of my burning bushes. 30 of them! They run down the lane to our propriety. They were right on our line. We didn’t see them do it, but they asked use several times to cut them back. I called the cops, he talked to them and they said that they did not do it. I believe they hired someone to cut them down and clean up the mess. These bushes were 15 ft. high. I don’t know if they will grow back. What can I do about this? The cop said that it looks like it might be a civil suit case. I don’t understand how, since we didn’t see them do it. I’m upset these bushes have been there for years. Thank you
