Police will take no further action against a youth who advertised the teeth and jaw of a dead whale for sale on Facebook.
Norfolk Police were contacted by internet users who had seen the page offering to sell 15 loose teeth and 11 still in the jaw for £5 each or £45 for the whole jaw.
The page was removed after the police were alerted to it.
A spokesman for the force said: "Following inquiries made, police can confirm it is likely at this time that no further action will be taken against a juvenile.
"Inquiries continue into other reports of the theft and sale of whale remains linked to the sperm whale washed up on the beach at Old Hunstanton."
The whale was found on the beach in Norfolk on Christmas Eve and has become a tourist attraction, attracting hundreds of visitors.
