The Daily Mail Online news report on 15 April 2016, mentioned that the male lion was spotted strolling down the streets of South Africa's biggest city in Johannesburg and it also added that the lion had been borrowed from a nearby lion park and the area was fenced off while the animal was let loose.

It is concluded that an old image of a tamed lion strolling in South Africa’s Johannesburg was shared with the false narrative that Russia is restricting the movements of its citizen leaving 800 tigers and lions across the country during the COVID-19 pandemic.
