Just seen a man destroy a herring gull nest - very angry!

Just taking my dog for an evening stroll and was surprised when a middle aged chap popped up on a bungalow roof and before I could get close enough to say anything he had pushed quite a large herring gull nest into a large container and climbed down. The resident birds were crying and circling in distress as he deposited the nest in his recycling bin. I do not know if there were any eggs. Is there any point in reporting this?
