Several trees at a nature reserve have been felled without permission, police have said.
Detectives believe the beech trees on Drayton Green Lane in Drayton, near Norwich, were felled on the evening of Tuesday, 6 May.
The force said it was treating the incident as criminal damage and urged anyone who may have seen suspicious activity after 19:00 BST to get in touch.
The area around the trees has been cordoned off until it can be cleared.
