JACKSON — The woman calling police was certain about what she was seeing.

"There is a baboon on my deck," the Jackson resident said about 2 p.m. this afternoon.

The call came 15 minutes after a driver reported seeing a baboon on the south side of I-195, prompting police and representatives of the nearby Six Flags Great Adventure Wild Safari park to rush to the woman’s house on Anderson Street, said township police.

Reportedly the size of a small dog, about two feet long, the primate with the red bottom took off into the woods before officials arrived, said police spokesman Lt. Andrew Cheney.

The woman’s street is about a half-mile from the outer limits of the 350-acre park, described on its website as the "largest drive-thru safari outside of Africa."

Baboon escapes have been rare over the past about 10 years when the park installed double-fencing, one of which is electrified, around the area, Cheney said.

Park officials were unable to be reached tonight, but police said park officials said they didn’t have a report of a missing baboon.

"They don’t have an accurate count on what they have because they have a bunch of babies," Cheney said.
