A monkey known as Banana Sam has been returned the San Francisco Zoo two days after he was stolen.

The thieves cut a back perimeter gate and took the 17-year-old squirrel monkey from an exhibit. But apparently they had no intention of keeping the primate.

He was later found in a park about a mile from the zoo Saturday evening. The man who found the monkey put him in his backpack, police said. He could receive a $5,000 reward that was offered for Banana Sam's safe return.

Jill Andrews, curator of primates the the San Francisco Zoo, said Banana Sam seems to be doing well despite his ordeal. The zookeepers are still on the lookout, though, worried that the monkey could have a caught a disease of some kind while he was outside the zoo.
