Authorities captured a diaper-wearing monkey who led them on a downtown search after biting a woman.

The 20-year-old woman reported being bitten on the thumb as she tried to pet the animal early Wednesday.

The woman was walking by State Street Brats, a popular nightclub, where a man had the monkey on a leash inside its beer garden. People walking by were petting the monkey, who was wearing a white diaper.

But the monkey bit the woman, who suffered four small punctures on her thumb, police said.

The bite sent the woman to the hospital, where a physician said the monkey should be found so that it could be quarantined to determine if it has a disease.

By 7:15 a.m., police found the man and the monkey. But the man lost the handle on the monkey before an animal control officer arrived and it got loose.

Police issued a warning to the public of the foot-tall monkey with a long prehensile tail: "It is now on the lam, presumably still in the State Street area."

About seven hours later, the monkey was captured and taken into custody downtown to be quarantined for 10 days, police said.
