A man hid a camera pen inside an empty juice can to film a woman as she used the toilet.

Gordon Adam was helping the woman and her husband renovate a student flat in Dundee when he tried to make the video.

Adam waited until the 37-year-old woman, who cannot be identified for legal reasons, was about to go to the toilet before setting up the camera.

He took the pen, fitted with a tiny camera lens in the top, and placed it inside an empty 7-Up can, which he propped up between a tap and basin on the edge of the bath.

The woman told a trial at Dundee Sheriff Court on Tuesday that she was using the toilet when she spotted the device.

She said: "I thought it was odd so I had a closer look and there was a blue light on the top of the pen and then I noticed there was a lens pointing at the toilet.

"When I saw the light flashing I just knew it was a camera. I could hear Gordon Adam in the hall asking my husband if I was still in the bathroom. I felt shocked, sick and dizzy - I didn't know what to do.

"I picked it up and took it out and gave it to my husband. I said ‘that's a camera pen’. Gordon came in from outside and said 'that's my pen - I found it in a taxi'.”

The woman's husband, 42, who cannot be identified, told the court that Adam then started "stabbing" at the pen with a screwdriver.

He said: "He actually injured himself while stabbing at it, he cut his hand. He then got a hammer and was attacking the pen with that and the screwdriver trying to break it open.

"Then he took all the broken pieces and said 'it's just a USB pen' and threw them in the bin."

Adam, 50, later claimed in a police interview that he had set the camera up in a bid to film the husband as a joke.

In his interview, he said: "I wanted to make a DVD and add a caption saying it was him at his best."

Asked by PC Scott Menmuir, of Tayside Police, for his reaction when he discovered the woman had found the camera, he said: "I panicked because I knew what it would look like. I tried to deny everything and burst the pen with my hand then smashed it open with a screwdriver. I wanted to destroy anything with her on it."

Adam, of Hilltown Terrace, Dundee, denied a charge of breaching of the peace by positioning the camera in the bathroom with the intention of recording indecent images without the woman's knowledge or consent.

Sheriff Elizabeth Munro found him guilty, deferred sentence until October 11 and placed him on the sex offenders register.

She told Adam: "I can only imagine how awful it must have felt for that woman - she must have felt defiled. I'm satisfied that you tried to make these images for sexual gratification."
