Police took 30-year-old Cory McGilloway into custody, San Francisco police Lt Scott Ryan told reporters on Friday.
McGilloway, whom investigators had identified as a suspect in the lemur's abduction, was arrested on Thursday evening by San Rafael police on unrelated charges. He was expected to be transferred to San Francisco County Jail to be booked on charges of burglary, grand theft of an animal, looting and vandalism all related to the lemur theft, Ryan said.
Police did not provide other details, saying the investigation was still underway but credited a multi-agency effort and tips on a public tip line that led to the suspect's capture.
San Francisco Zoo director Tanya Peterson said Maki was "an ageing wild animal who needed special care" for ailments including arthritis. "He's still agitated, dehydrated and hungry," she said, adding that veterinarian teams were working to get him back to health. Due to his travels, she added, "He's socially distancing from his primate family" but would hopefully join the other lemurs soon.
Authorities had offered a $3178 (US$2100) reward for locating Maki, which the zoo will be giving to the church.
"I understand there is a young boy there who witnessed this and also called in the tip, and we are giving his family a free membership to the zoo," said Peterson, who thanked the boy and everyone who helped. "They literally saved a life."
