Cecil the Lion's brother Jericho has been killed by poachers in Zimbabwe.
American dentist Walter Palmer, from Minnesota, sparked outrage around the world when he killed popular 13-year-old Cecil with a bow and arrow last month.
Jericho, who had been protecting his brother's pride, was reportedly gunned down this afternoon in Huwange National Park.
The Zimbabwe Conservation Task Force said: "It is with huge disgust and sadness that we have just been informed that Jericho, Cecil's brother, has been killed at 4pm (3pm BST) today.
"We are absolutely heart broken. We will update you all as soon as we have more details."
It comes after Zimbabwean wildlife authorities announced that they had suspended the hunting of lions, leopards and elephants in an area favoured by hunters.
Bow and arrow hunts have also been suspended unless they are approved by the National Parks and Wildlife Authority's director.
The death of another lion in April is being investigated after the authority received information this week.
Zimbabwean authorities are seeking Mr Palmer's extradition from the United States on illegal hunting charges.
