A Zimbabwe conservation group says it wants the head of Cecil the Lion to be mounted in a case in Hwange National Park, where he was killed last month.
Johnny Rodrigues, chairman of the Zimbabwe Conservation Task Force, said Cecil’s head was found in the home of Theo Bronkhorst, one of the co-accused.
Cecil was shot in July by US dentist Walter Palmer. Zimbabwe is seeking his extradition.
The death made headlines around the world, sending Mr Palmer into hiding.
Mr Rodrigues told the BBC the plan had been for the head to be sent to South Africa and then on to the United States where Mr Palmer would be able to claim it.
But it was seized by police on 7 July from the home of Mr Bronkhorst, a guide on the illegal hunt attended by Mr Palmer.
