An Essex Police spokeswoman said officers would be returning to areas where a lion had been spotted during daylight hours to look for signs it had been there, such as pawprints.
Donna Veasey from Essex Police said they will search the area around the village of St Osyth this morning for signs of the lion spotted by a member of the public last night.
Essex police are still searching for the lion, reportedly sighted by a member of the public last night in St Osyth in Essex.
Officers will be visiting areas of sightings this morning to check for paw prints.
A resident of St Osyth, where a lion was reportedly spotted by a member of the public, told ITV News they were worried for the safety of the lion, and did not want it to be hurt, or shot dead.
Dave Sparks runs the Red Lion pub in Essex, near where a lion was reportedly sighted by a member of the public yesterday evening.
He said his bank holiday Sunday evening was a bit surreal.
Residents in St Osyth are returning to their homes on the advice of Essex police after a lion was sighted in the area. Che Kevlin told the BBC he heard the lion roar whilst out walking his dog:
I heard a loud roar at 10pm. It sounded like a lion. It was worrying as we had just been for a walk with the dog. We saw the police helicopter but thought it was just searching for a person.
It sounded like the roar of a lion. We have field and wood just behind our fence, so you never know,
Essex Police had advised residents living in the St Osyth to stay indoors after police received reports of a lion being seen in a field. It is not know where the lion may have came from.
Essex Police say they are working with experts from Colchester Zoo, so that they can tranquilise the animal when it is found.

Essex police have said the lion had not escaped from the Colchester Zoo, as all of its animals have been accounted for.
It is still not clear where the lion, if that it what it is, came from although a circus had been performing in the Clacton area.
