Geraghty-Shewan went to take a photo of his son on a ride and was suddenly stopped:
“Ben spotted a children’s ride which had a train on it and wanted to have a go because he’s obsessed with trains.
“When he got on my wife suggested we take a picture of him.
“I took the picture on my phone and suddenly this security guard came up and told me it wasn’t allowed because I could be a paedophile.
“I told him Ben was my own son. But he said I couldn’t prove it. He said there is a real problem with paedophiles and that if I didn’t like it, he’d call the manager.
“A few minutes later a policeman walked in and approached me, so they must have been tracking me on the CCTV.
“He said he’d received a complaint that a man matching my description was taking pictures of children and wanted my name and address.
