Joggers in the east of Tarragona, had a surprise on Tuesday morning when they sighted a female lion near the frontier area of Teruel, Tarragona.

The police responded by launching a large operation to locate the animal, using helicopters to look for the fierce predator.

The origins of the lion are unknown at the moment, although it is speculated that the lion may have been an illegal pet, or a runaway animal from a circus.

Veterinarian Cati Gerique cautioned people that if they come across the lion, they should try to remain calm and avoid making any fast moves.
