This is "Toni", a male orangutan at the same bankrupt zoo looking in through bars to the dark room where Tini is imprisoned.
Toni is suffering a mental disorder through being kept in this bare concrete enclosure for years. He has to remain outside in all weathers 24/7. People shout at Toni, through bottles at him, and rubbish into his enclosure.
In the second photo, if you look closely you can see Tina on the other side of the bars.
