The huge beast was spotted in a river in the municipality of Simancas, in the central Spanish province of Valladolid. Experts believe the animal could be a Nile crocodile that can weight up to 200 kilogrammes, 31.5 stone. A video shows officers of the Spanish Civil Guard searching for the reptile that was sighted by two different people on the same day.
Police left bait to attract the crocodile, in an attempt to catch the beast – or at least record footprints to help “follow its movements”.
The crocodile, measuring about 2 metres, 6.6 feet, was seen at Pesqueruela, where there is the confluence of the Pisuerga and Duero rivers.
It has been reported a person walking on the riverbank suddenly saw the crocodile.
They immediately reported the sighting to Spanish authorities.

The river is frequently used by members of the public.
