May 26 (UPI) -- Police responded to an affluent London neighborhood on a report of a "big cat" with cheetah-like markings and determined the animal was a domesticated Savannah cat.
Residents of the area unofficially known as Billionaire's Row, located in the Hampstead Heath-East Finchley area of London, called police Monday night to report a big cat was on the loose.
"It was elongated, really too big for a domestic pet. The markings were like that of a cheetah or leopard," a resident who spotted the feline told the London Evening Standard.
An armed police unit was dispatched to the neighborhood and an animal expert accompanying the officers was able to catch a glimpse of the animal and identify it as a Savannah cat, a domesticated hybrid of a domestic cat and an African serval.
Police said the animal escaped into the undergrowth before they could capture it. The cat, which is believed to have escaped from a home in the area, remained at large Tuesday.
