Grant Miller, senior officer on the Convention on International Trade of Endangered Species (CITIES) Border Force team at Heathrow has said the market in endangered animal items being trafficked into the country is evolving.
He said there is a significant increase in items in such as ivory from west and central Africa being trafficked through London's "logistic hub".
"We pick up between 5-15 kilo of ivory at time. The heartbreaking thing is it quite clearly new ivory from recently slaughted elephants."
