"Night Hawking", people using metal detectors illegally, is a Heritage Crime, which is "any offence which harms the value of England’s heritage assets and their settings to this and future generations."

Officers said Night Hawkers rarely hand over any finds that they make, and anyone who finds treasure must report it to the local coroner within 14 days of finding it.
