A woman was left shocked after looking out of her window to see a 4ft-long 'crocodile' on the loose.
Nurse Sarah Jayne Ellis spotted the animal, which has been dubbed the Castleford Croc, in a back garden in the West Yorkshire town.
Quick-thinking Sarah was able to whip out her phone and grab some quick snaps of the creature, which appear to show a long reptile with a tail lying in the grass.
Sarah said the animal was at least 4ft in length and 'looked real', but she didn't get a chance to investigate further as she'd just finished a long night shift and wanted to go to bed.
She said while looking at it the creature didn't move, but when she checked back a few hours later it had gone.
Speaking about her reaction to the alleged reptile, she told YorkshireLive: "I thought 'that's a crocodile'.
"I was shutting the blinds in the bedroom when I saw it on the grass. I looked a couple of hours later and it was gone."
Stunned Sarah then showed the photos to her sister-in-law Kate Eliis Holmes who was equally as shocked at the sighting.
Kate told the outlet: "I was just genuinely in disbelief when she was telling the story. When I saw the picture I was in disbelief.
"I thought it was bizarre and a really interesting story."
She added: "It definitely looks like a crocodile."
And this isn't the first time a rogue reptile has been spotted in Castleford - in May 2020 photographer Lee Collings says he saw what he believed to be a croc at the Fairburn Ings nature reserve.
Lee said he had heard rumours that someone had dumped a caiman - a smaller reptile belonging to the crocodile family - in the area.
Lee said at the time: "I am 46 years old and have been a birdwatcher for over 30 years, and I've never seen anything like this, other than a crocodile or alligator.
"It walked like it was rigid. It moved slow, but too fast to photograph it by the time I realised what I thought it was.
"It was 3ft to 4ft in length and about 4ins to 5ins high."
