Banana-Sam was resting comfortably behind the scenes at the San Francisco Zoo on Sunday, with staffers keeping close tabs on the squirrel monkey after his weekend kidnapping ordeal. 
  
 The 17-year-old primate spent New Year's Day recuperating out of the public eye after a nearly 40-hour adventure that began with his abduction late Thursday or early Friday. 
  
 The 2-pound creature was shaking, hungry and cold when police returned him to the zoo Saturday evening, but he was relatively clean and with no obvious trauma, said Danny Latham, a zoo spokesman. 
  
 "We have no idea the conditions in which he was kept," he said. 
  
 Latham said it was unclear when Banana-Sam would return to his exhibit with his 17 squirrel monkey friends. 
  
 "We hope very, very soon," he said. "I'm sure people will want to come and see him." 
  
 Banana-Sam gained worldwide fame as his abduction spread around the globe. A Twitter account that someone opened in his name, @SF_BananaSam, had more than 2,000 followers, with posts detailing his alleged exploits throughout the city. 
  
 A trip to the monkey bars in Golden Gate Park was apparently disappointing. 
  
 "I was never cut out for life on the outside," read one post following his return. "3 hots and a cot for me!" 
  
 On Sunday, police continued to investigate the case. They said a visitor to Stern Grove in the Sunset District found the monkey and coaxed him into a backpack Saturday evening. 
  
 A $5,000 reward for the monkey's safe return had not yet been paid out, Latham said. 
  
 The kidnappers apparently knew where they were going and what they were doing. They climbed on a roof to cut through netting to nab Banana-Sam, making off with the animal despite guards and security cameras. 
  
 "Regardless of how many feet or eyes you have, if someone is willing to do something, they're going to find a way to do it," Latham said. 
  
 Still, the zoo has beefed up security on the graveyard shift since the incident. 
  
 "We're just happy that it turned out the way it did," Latham said. "It's a very happy story."

 Banana Sam was "hungry, trembling and thirsty," after police returned him to the zoo, but a full physical examination showed he was healthy, zoo spokesman Danny Latham said in a statement. 
  
 Banana Sam's theft Thursday prompted the zoo to boost security and keep the other 17 squirrel monkeys indoors. 
  
 He was taken after thieves cut through a gate and made holes in the mesh surrounding the monkey exhibit. 
  
 The 17-year-old monkey was found at Stern Grove, a park about a mile (1.6 kilometers) from the zoo, police spokesman Carlos Manfredi said. 
  
 The monkey was found by a bystander who saw him come out of the bushes. 
  
 "He managed to coax the monkey into his backpack," Manfredi said. 
  
 The man called police, and within an hour they met with zoo officials, who verified the monkey's identity. 
  
 "We are so thankful to the community and to the San Francisco Police Department for this happy ending," zoo director Tanya Peterson said in a statement. "I know it's been extremely stressful for zoo staff during this time but we are grateful Banana Sam is back at the zoo where he belongs." 
  
 No one has been arrested and no suspects have been identified. 
  
 "We're looking at every possible avenue, including the bystander," Manfredi said. 
  
 A $5,000 reward had been offered for his safe return. 
  
 The two-pound (900-gram), one-foot-(90-centimeter-)tall Banana Sam is an elder among squirrel monkeys, whose lifespan is about 20 years. 
  
 Common squirrel monkeys like him are not endangered, and are often seen in pet markets and medical research. While some states allow keeping monkeys as pets, in California it is illegal. |||||

A monkey simian-napped from the San Francisco Zoo was returned by a man who said he coaxed the animal from the bushes at a nearby park into his backpack. The 17-year-old spider monkey, Banana Sam, was "hungry, trembling and thirsty," but healthy, said a zoo worker. He was missing close to 40 hours. The kidnappers had climbed onto a roof to cut through netting to grab the monkey, despite guards and security cameras at the zoo. "We're just happy that it turned out the way it did," a zoo spokesman told the San Francisco Chronicle. A $5,000 reward for Banana Sam's safe return hasn't been paid out yet. Police are continuing to investigate. "We're looking at every possible avenue, including the bystander," a police spokesman told AP.
