When I was a young RAF airman I was stationed at Butterworh airbase in Malaya. One of our number owned a macaque which was anchored by a waist belt to a cable stretched between two palms. The beast frequently broke free and attacked and bit airmen. Reluctantly, the owner accepted the monkey had to go.
He made a small cage and secured the monkey on the pillion of his motorcycle, left the base and drove north about 20 klicks and released the animal into the roadside forest where in scampered away into the trees.
Returning to base he dismounted to find the monkey sitting on the pillion, snarling and raising its eyebrows.
Then it bit him.🤣
