A stalker secretly photographed two women and crept into one victim's bedroom.

James Don had denied carrying out lengthy campaigns of harassment against the pair but a jury took just 26 minutes to find him guilty unanimously.

Don, 59, of Fullarton Street, Dundee, was given a four-year sentence for breach of the peace and two charges of stalking at addresses in Dundee between January 2004 and March 2015.

His trial was told he had got into one of the women's homes and went through her underwear without her knowledge.

The woman, who cannot be named, told a jury she had been left "terrified and violated" when police showed her pictures and videos Don allegedly took in her bedroom without her knowledge.

Sheriff Lorna Drummond told Don he had committed "particularly horrifying" offences.

She imposed a four-year extended sentence, with three years to be served in jail and a year on licence and also placed Don on the sex offenders register indefinitely.

The sheriff said: "You went to the lengths of entering the privacy of one woman's home uninvited and videoed her bedroom and took photos of her underwear.

"That is particularly horrifying, that you invaded the sanctity of her home.

"It is clear to me that your behaviour has had a devastating impact on these women."

The first victim, aged 36, told Dundee Sheriff Court she had previously worked with Don's wife but had not done so for several years.

The woman called in police repeatedly because of Don's regular, unwanted appearances at her workplace.

She said she was "oblivious" to the cache of surveillance images being taken of her or the fact Don had been in her house and her bedroom.

The court was shown dozens of pictures found on cameras and memory cards found in Don's home when it was searched last year.

One video showed the inside of the woman's bedroom, with the cameraman filming around the room before spotting a bra hanging from the end of the bed and pulling it to his face.

The court was also shown dozens of still images of the woman apparently taken of her at work using a camera with a zoom lens.

A series of videos were also shown to the jury, showing her sweeping at the front door of the business she worked at from a distance of around "five car lengths".

The court heard Don's second victim was repeatedly tailed between December 2010 and February 2006.

Don also repeatedly turned up at locations where he believed she may be and took covert observations and photos and videos of her.

The court heard the woman was completely unaware of the extent of Don's stalking until police visited her and showed her a series of long lens pictures he had taken of her.

Defence solicitor Ian Houston said: "He is hoping that the period of imprisonment won't be so long to end his marriage."
