People are claiming to have seen a "ghost" in a window behind a councillor in a picture being widely shared online.
The photo taken in Caernarfon has been a huge source of debate.
Councillor Jason Wayne Parry arranged for this photo to be taken on the Peblig Ward.
He wanted the picture snapped in a bid to highlight problems with the 'dog mess' on the streets.
But when he shared the photo to Facebook to raise awareness, the response he received wasn't what he was expecting at all.
Some people said they could see a strange 'ghostly' figure standing in the window of one of the homes in the background of the picture,
Cllr Parry, who owns Magic Clippers Gwallt Co in the town, said: “I was putting up signs warning against dog fouling in the area to bring attention to the problem we have in the estate.
“When I do jobs like that, I like to take a photo and share it on my Facebook page to let people know what's being done.
“I was leaving work the other day and someone ran up to me and asked if I had noticed anything strange about the photo I'd put up.
“She had said it was her friend's home in the background of the photo and while they were looking at it, they noticed something unusual in the window.”
Curious, Cllr Parry decided to enlist the help of a friend who works as a TV editor to help shed some light on the mystery.
It was only when the photos were enhanced that in Cllr Parry's own words "it became obvious there was something there."
Shocked, Cllr Parry sent it to the woman who currently lives in the at the address who then duly posted it online
The image has attracted a flurry of speculation as to what - if anything - is in the window.
Some say they see the image of a little girl or a woman.
Others however have dismissed it as a simple optical illusion.
