In an unusual incident, California police found themselves in a "monkey business" Saturday night when they received a 911 call from a zoo.

Before the conversation could start, the call got disconnected from the other side. Following this, the cops tried to reach out to the number with a call and text, but there was no response, NBC News reported.

This prompted the police to rush to the location to investigate any possible emergency.

"It all started Saturday night when we received a 911 call that had disconnected. Dispatchers tried to call and text back but they received no response. So Deputies were sent to investigate," the San Luis Obispo County Sheriff's Office said in a Facebook post Monday.

To their surprise, the address took the deputies to a zoo near Paso Robles. Upon reaching Zoo to You, they headed to the office, only to find that there was no one in trouble.

The police went on to discover a mischievous Capuchin monkey named Route seemingly dialed 911 from a zoo cellphone found in a golf cart.

"Apparently, Route had picked up the zoo's cell phone... which was in the zoo's golf cart... which is used to travel around the zoo's 40 acre site," the post added.

Route happened to dial the right combination of numbers, which resulted in the deputies reaching the zoo for a probe.

"We're told Capuchin monkeys are very inquisitive and will grab anything and everything and just start pushing buttons," the office's social media post added.

In an interview with "As It Happens" guest host Susan Bonner, Lisa Jackson, assistant director of Zoo to You, said the police winded up with a "smile on their face" after the incident.

"They said it was much better coming to where they thought there was something wrong and winding up with a smile on their face," said Jackson, CBC News reported.

Jackdon added the Capuchin monkey was a regular passenger in her golf cart, always playing around.

"She's always inquisitive and so I thought nothing of it. Took the phone, put it back, and then her and I went about our business," she said.

The zoo keeper further pointed out Route reached the rescue compound of the zoo after her parents were poached.
